3-1-1 Rule for Liquids in Carry-on Bags

Find out what's allowed before you pack

When you're going through airport security on your next vacation or business flight, you might notice a posted rule by the Transportation Security Administration called the 3-1-1 Rule, which dictates how much liquid travelers are allowed in their carry-on bags. Still, you might not understand exactly what this regulation means for your traveling needs.

The 3-1-1 Rule refers to three core components that govern how many liquids you can bring in your carry-on bags: Each liquid must be in a 3.4-ounce or less container ("3"), all containers must be placed inside one clear quart-sized plastic bag ("1"), and each passenger is only allowed one plastic bag ("1").

In sum, the 3-1-1 Rule states that you can carry as much liquid as can fit inside 3.4-ounce containers that fit inside one plastic quart-sized bag; however, you can bring as much liquid as you feel comfortable carrying in your checked bags as long as these liquids do not violate other TSA regulations that dictate what you can and cannot fly with in general.

How to Pack Your Liquids in Carry-ons

Whether you're hoping to bring your favorite shampoo or conditioner on your weekend trip or need to take contact solution on your flight, you'll need to properly pack liquids to get them through the TSA security checkpoint without hassle.

You'll want to start by either buying travel-size bottles of your favorite products or by purchasing travel toiletry bottles , which you can buy online, at most supermarkets, or home goods stores, and filling them with enough of your favorite products to get you through your trip. Then pack each of these inside a quart-sized ziplock (or other sealable) plastic bag—you should be able to fit four or five.

It's recommended that you pack this bag of bottles in your carry-on last, on top of your clothing and other times, because you'll need to pull the bag out and put it in one of the security checkpoint bins to pass through the X-ray machine. You can also stow it conveniently in an outside zip pocket for easy access.

Liquids That Are and Aren't Allowed

You might be surprised to learn that you can bring travel-size bottles of alcohol in your carry-on or that you can't carry creamy dips or spread as a snack in your suitcase if it exceeds 3.4 ounces, but knowing these rules will help you avoid additional screening at the TSA checkpoint.

You can bring blenders (with blades removed), alcoholic beverages less than 3.4 ounces that do not exceed 70 percent in alcohol content, baby food, some canned foods, and even live lobsters, but you cannot bring gel heating pads, any wet foods that exceed 3.4 ounces, ice cream of any quantity, or firearms of any type. 

For a complete list of all items that are forbidden and permitted through TSA security checkpoints at airports, make sure to check out the TSA website before your flight—you can even snap a picture of an item you're questioning and ask them on the TSA Facebook page whether or not it is allowed.

How to Pack a Carry-On Bag

Here's the 411 on the TSA's 3-1-1 liquids rule

We've all been there. Waiting in the Transportation Security Administration line only to hear agents call for a "bag check," often because a traveler had a liquid product in their carry-on that's over the allowed limit (or some sort of other prohibited item).

It's a process that can sure slow things down, particularly on the busiest travel days. As you pack for your trip and consider what to put in your carry-on or checked luggage, it's important to consider what the TSA's limits are for liquids and similar products.

Since September 2006, the TSA has gone by the 3-1-1 rule when it comes to those types of products, including items like toothpaste, shampoo, conditioner, mouthwash and lotion -- sunscreen included.

For more TPG news delivered each morning to your inbox, sign up for our daily newsletter .

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

If you meet those requirements, you should get through security without issue. However, if your liquid items are larger than 3.4 ounces each, you'll have to leave them in your checked bag.

There are a few exceptions, though.

The TSA has kept in place a temporary pandemic exception to the rule, allowing up to 12 ounces of liquid hand sanitizer in carry-on baggage.

Part of this exception: The hand sanitizer will have to be screened separately since it's technically over the limit. You'll need to remove it from your bag before it goes through the scanner.

There are also exceptions for larger amounts of medically necessary liquids, gels and aerosols. You can bring those products in larger, "reasonable" quantities, the TSA's website says. However, you must declare those items to security officers at the checkpoint for inspection.

This could, obviously, take a little more time than if you're traveling without those items.

This exception doesn't include sunscreen, despite calls to relax sunscreen restrictions at TSA checkpoints. Like other liquid products, sunscreen bottles over 3.4 ounces must go in your checked luggage.

There are also many liquids you cannot bring with you .

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup and yogurt as long as they are in a container of less than 3.4 ounces according to the TSA .

Related: Should you get TSA PreCheck or Clear — or both?

And yes, you can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport, since -- as the TSA points out -- many airports have filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

Everything You Need to Know About the TSA’s Liquid Limit

The tsa allows liquids under 3.4 ounces in your carry-on—but what’s considered a “liquid” isn’t always obvious..

Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

• Shampoos and conditioners
• Lotions and sunscreen
• Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

Buy Now: GoToob three-pack of 3.4-ounce bottles, $30, rei.com

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric. Like GoToob, they’re leakproof and easy to fill, but thanks to their flexible, fabric-like design, they will shrink to their contents, taking up less space in your pack. >> Read the full review of the Matador FlatPack

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

Everything You Need to Know About TSA Liquid Rules

Here's what to know before you fly with shampoo, medication, or any other liquids you may need during your travels.

Dealing with airport security can be one of the more daunting aspects of air travel , from the detailed rules about what you can and can't bring on board to the long lines that often form at checkpoints.

One rule that frequently trips up travelers is the Transportation Security Administration's (TSA) 3-1-1 regarding liquids in carry-on bags . We're here to walk you through the finer details of the rule and provide helpful tips for packing liquids when you're flying.

What is the TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Liquids that do not comply with the 3-1-1 rule must be packed in checked bags, or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags. You can find a full list of permitted and prohibited items on the TSA's website .

If you're unsure if a specific item adheres to the 3-1-1 rule, you can always contact the TSA before your trip. "Tweet your questions and comments to @AskTSA or via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," TSA spokesperson Jessica Mayle tells Travel + Leisure . "You can also call the TSA Contact Center at 866-289-9673."

Are there any exceptions to the 3-1-1 rule?

The TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," says Mayle. "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

And that's not all. "There's an exception for hand sanitizer, which has a temporary 12-ounce limit," says Mayle. But as COVID-19 travel restrictions and protocols continue to lift, the temporary special case for hand sanitizer could change, too.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports , you can bring nonalcoholic drinks and other liquid items purchased airside onto your flight. (This is not always the case in international airports.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding — sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

Packing Tips for Liquids in Carry-on Bags

• While many products are sold in 3.4-ounce containers suitable for travel, not all of them are. Consider rebottling your liquids into travel-size, leak-proof cases.
• "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T+ L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo."
• Buy your liquids, like shampoo or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
• On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
• Pack your nonliquid toiletries separately to save space in your quart-sized bag.
• Pack your liquids bag in an easy-to-access space, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really  100 ml comes out to 3.3814 fluid ounces. )

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces .

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check , you can take advantage of several benefits including things like:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry ( read how to get approved here ).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste , lotion , sunscreen, shaving cream, shampoo , conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant . For example, the following types of deodorants will be subject to the 3-1-1 rule:

• and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

• Liquid chocolate
• Creamy dips and spreads
• Mashed fruits such as applesauce
• Jam and jelly
• Maple syrup
• Oils and vinegars
• Peanut butter
• Wet pet food
• Salad dressing
• Salsa and sauces

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand , chances are you can bring it through.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications .

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane . In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some  ranges  for the alcoholic content of some common beverages:

Alcohol Percentage Content

• Vodka | ABV: 40-95%
• Gin | ABV: 36-50%
• Rum | ABV: 36-50%
• Whiskey | ABV: 36-50%
• Tequila | ABV: 50-51%
• Liqueurs | ABV: 15%
• Fortified Wine | ABV: 16-24%
• Unfortified Wine | ABV: 14-16%
• Beer | ABV: 4-8%
• Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

• The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
• The original receipt for the liquids is present and the purchase was made within 48 hours.

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

The same liquid rules apply for both domestic flights and international flights. One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details. Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

No, you do not have to take out your liquids if you have TSA Pre-Check.

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United. With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

If you are traveling from an “international last-point-of-departure” to the U.S ., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin. TSA recommends that you transport powders in your checked baggage.

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

The TSA Liquids Rule for Carry-on Bags (3.4 ounces)

Understand these rules so you don’t get held up on the TSA security line!

TSA 3-1-1 Rule

Exceptions to the tsa liquids rule, tsa liquids rule for precheck, does tsa consider makeup a liquid, converting 3.4 oz to ml – how many ml is 3.4 ounces, what does 3.4 oz (100 ml) look like, converting 100 ml to oz – how many oz are in 100 ml, 100 ml to cups, 100ml bottle size – how big is a 100ml bottle, wrapping up: tsa liquids policy, more carry-on content:.

Before you finish packing to head to the airport, always double-check your carry-on bags and make sure you don’t have any bottles or other items that don’t comply with the TSA liquids rule, (known as the 3-1-1 rule).   

By the time the TSA finds that expensive bottle of perfume or lotion in your bag, it’s too late and you’ll have to say goodbye and hand it over to get through security and board your plane on time.  It’s happened to my family many times and could easily have been avoided with a quick check before leaving.

To help make sure this doesn’t happen to you, we’ve created this article that will tell you everything you need to know about the TSA liquids rule, including how much liquid is 100 ml, what are travel-sized bottles, what is considered a liquid, etc. Basically, all the stuff that could get confiscated when making your way through airport security.

What’s the TSA Liquids Rule?

The TSA liquids rule states that you can bring a quart-sized bag of liquids, aerosols, creams, gels, and pastes in your carry-on bag and through the airport security checkpoint. However, you are limited to containers that are travel sized and contain less than 3.4 ounces (100 milliliters) per item.

Items that are in packages or bottles larger than 100 milliliters (or 3.4 ounces) will have to go in your checked luggage .  In addition to larger liquids, any liquid that is more than 3.4 oz or 100 ml and is not contained in a secure, tamper-proof bag must be packed in your checked luggage.

Each liquid must be in a 3.4-ounce or less container (“3”), all containers must be placed inside one clear quart-sized plastic bag (“1”), and each passenger is only allowed one plastic bag (“1”).

There are 2 exceptions to the TSA 3-1-1 Liquids Rule

• Medications, and
• Infant/Child nourishment

Medications larger than 100ml

TSA allows larger-sized packages of medical liquids, gels, and aerosols in your carry-on. This also includes medical accessories such as freezer bags, pumps, syringes, etc. These items do not have to be in a plastic zip lock bag, but you will have to declare these items to TSA officers at the checkpoint prior to inspection.

Here’s a video that provides all the details you need about traveling with medication.

Formula, Breast Milk, and Juice

Formula, breast milk, and juice for infants and toddlers are allowed through the security checkpoint. These can be in quantities greater than 3.4 ounces or 100 milliliters and are allowed in carry-on baggage.

Similar to medications, just inform the TSA officer of what you have and remove the items from your carry-on bag so they can be screened separately from the rest of your belongings.

Ice packs, freezer bags, frozen gel packs, and other accessories required to cool formula and breast milk are allowed in your carry-on bag.

The TSA PreCheck Program allows registered travelers the ability to go through expedited screening lines at over 200 participating U.S. airports with over 80 participating airlines. Once you are approved in the program you don’t need to remove your 3-1-1 liquids from your bag.

Actually, you can avoid removing any of the following items during the screening process:

• 3-1-1 compliant bag
• Light jacket/Sport coat/outerwear
• Laptop / iPad from bag

To apply for PreCheck, go to tsa.gov/precheck . From here you can enroll and make an appointment online or walk in at any one of over 380 enrollment centers . It can take up to 30 days to obtain a TSA PreCheck known traveler number.

What does TSA consider a liquid?

According to TSA guidelines, any substance that is free-flowing or viscous is considered a liquid. This includes liquids, aerosols, pastes, creams, and gels.

According to the TSA, “Makeup in a solid or powder form is allowed in carry-on and checked bags with no quantity or size limitations. However, when packed in carry-on bags, makeup in a liquid, lotion, gel, paste, or creamy form, must be in containers that are 3.4 ounces or less. You can take as many travel-sized liquids as you can comfortably fit into one quart-sized, zip-top bag.”

When it comes to makeup, the following are some examples of liquid cosmetics:

• Nail polish,
• Moisturizers,
• Foundation,
• Mascara, etc.

How much is 3.4 oz?

Now that you understand the basic concepts of the TSA liquid rule, it may help to have an idea of what constitutes 3.4 oz or 100 ml, since most people don’t naturally know how big a 3.4-ounce container or a 100 ml bottle is.

So if you’re wondering exactly how much is 3.4 oz or how big is a 100 ml bottle, we will walk through that for you here.

3.4 ounces (oz) converts to 96.388 milliliters (ml). For purposes of simplicity, the TSA rounds this up to 100 ml

Most of the toiletries you would bring on a trip come in travel-sized packages that can be bought at any drug store or grocery store. These travel-sized items are typically 3 ounces (90 ml) and generally provide enough lotion, shampoo, or toothpaste for a 5-day trip. If you’ll be traveling longer, you may need to stock up on a couple of extra bottles or plan on purchasing more upon arrival at your destination.

100 milliliters (ml) converts to 3.3814 ounces (oz). For purposes of simplicity, the TSA rounds this up to 100 ml

100 milliliters (ml) converts to .422675 cups, so it’s just under 1/2 cup.

A 100 ml bottle is fairly small. To give you a visual, look at the image below that shows a 500 ml water bottle vs. a 100 ml spray bottle. The 100 ml bottle is about 3 inches tall and the water bottle is about 8 inches tall.

Hopefully, this guide will give you a better idea of what the TSA considers a liquid and what size they will let you bring on your carry-on. Knowing this information in advance can save a lot of headaches at the airport!

The TSA Liquid Limit You Need To Know For Airport Security

Last Updated on November 1, 2021

There are actually three TSA liquid limits for fluids, gels, pastes, and creams packed in your carry-on bag.

These liquid limits are enforced by the TSA when going through airport security.

The limits are not about the moment that you step on the plane. They are about the moment your bags go through the scanners at the security checkpoint.

Liquids that you buy after the airport security checkpoint can be brought onto the plane without restrictions.

Let’s look at the checkpoint guidelines and the three limits.

The Liquids Limit – TSA Rules & Guidelines On Bringing Fluids On Planes

Transportation Security Administration’s official website outlines its liquid rules, but they don’t do a very good job of explaining why the liquids limits are in place.

The contents of your carry-on bag will be scanned by the x-ray machine. Crucially, the TSA cannot identify from the scanner whether liquids really are what they say they are on the label.

The x-ray scanners can detect weapons, but they can’t detect flammable liquids.

Any passenger’s liquids could be explosives in disguise. This is why they are a security threat and why the TSA liquid limits exist. They want to make sure nobody is bringing a lot of liquids on the plane, just in case.

Here are the three liquid limits that the TSA imposes.

TSA Liquid Limit 1 – Only Travel Size Containers

You must carry liquids, gels, and aerosols in a travel-size container.

Travel-size means bottles that are 3.4 oz or less. If you are thinking 3.4 ounce is a strange number it’s exactly 100 ml and that is the standard maximum size of carry-on liquids around the world.

Check this post if you want to get a feel for what 3.4 oz looks like .

It is the size of container that is important, not the amount of liquid in the the containers. So half empty tubes of toothpaste don’t qualify.

Generally, larger containers with more than 3.4 fluid ounces cannot be packed in carry-on luggage.

If you exceed the liquid limit TSA will confiscate it and throw it in the trash. Although, the TSA prefers to say you “voluntarily surrender” the liquid since you could, in theory, choose not to fly.

TSA Liquid Limit 2 – A Quart Size Bag

All your travel-size bottles must be packed in a one quart sized bag .

There are 32 ounces in a quart, but you won’t be able to pack 32 ounces of liquids in your hand luggage. The shape of the bottles makes it awkward to pack a Ziploc baggie to the maximum.

The total liquids limit for the TSA is probably around 25 ounces. That would be 7 or 8 travel-size bottles packed in a quart-size plastic baggie.

The TSA says a 6 x 9 inches Ziploc bag is quart-sized, but there are other bag shapes that are suitable.

Go ahead and adjust the dimensions of the ziploc bag to find out if it's quart-sized and TSA approved.

You could also buy a reusable “quart size” bag from amazon. Most of them are actually larger than one quart but everyone seems to be getting away with it .

TSA Liquid Limit 3 – Only One Quart Bag Per Passenger

The 3-1-1 TSA rules only permit one plastic quart bag per passenger , that’s another limit, it’s not one bag per carry-on suitcase. So you can’t get around the TSA liquid limits by bringing more than one carry-on.

The 3-1-1 Rule

We can now see why it’s called The 3-1-1 Liquids Rule. There are 3 TSA liquids limits.

• Three point four ounces travel size bottles – the container size limit.
• In a one quart size plastic bag – the plastic bag size limit.
• And only one bag per passenger – the number of bags limit.

The TSA 3-1-1 rule is kinda confusing if you ask me. It should be called The 3.4 – 1 Rule but then that wouldn’t have been as catchy.

What does the TSA consider to be a liquid?

The TSA often says “If you can squeeze it, smear it, pump it, spread it, spray it, or spill it then it’s considered a liquid”.

That means that some items that you might not think are liquids are considered to be liquids by the TSA security officers.

A lot of travelers are caught out by spreads, creams, and gels. In the mind of the average person, something that doesn’t pour isn’t a liquid, but that’s not how the TSA defines it.

It can also matter whether the liquid is “flying solo” or is part of something.

For example, liquid food fillings that are part of solid food don’t count as liquids.

The classic example is peanut butter . Peanut butter in a jar is considered a liquid, whereas a PB&J sandwich is considered a solid.

And remember this from science class, frozen liquids become solids.

That’s true at the airport security checkpoint too.

Liquids that are restricted at room temperature become unrestricted if they are frozen solid. That means if a liquid is frozen the 3.4 oz limit does not apply. The challenge is getting the liquid to the airport while it is still frozen solid. The TSA will refuse to let it past if it is beginning to melt. Ice packs, coolers, and perhaps dry ice could help.

Some items that passengers get caught out by are gel packs, canned foods, snow globes, bug spray, and sunscreen.

Liquids That Are Never Allowed Through Security

There are some liquids that are never permitted on the plane even in travel-size bottles.

You cannot bring hazardous materials (Hazmat) flammable liquids on to the plane even in quantities smaller than 3.4 oz.

Examples are:

• Aerosols that are not toiletries
• Paint thinner
• Lighter fluid
• Lighter gas

Only travel-size aerosols that are toiletries are permitted in hand luggage. The definition of a toiletry is something that is sprayed on your skin. So aerosol deodorant is permitted, but aerosol air freshener is not.

Exemption To The TSA Liquids Limit

There are some liquids permitted in carry-on baggage in containers larger than 3.4 ounces

Liquid Foods For Babies & Infants

Feel free to bring water, juice, or soup for an infant.

You also don’t need to worry about breast milk or baby formula.

You simply put these items in a separate bin at for screening at the checkpoint.

When a child is able to walk through airport security unassisted by an adult they are no longer considered an infant and the exemption ceases to apply.

Medically Necessary Liquids

You can also pack reasonable quantities of medically necessary liquids in carry-on bags in containers larger than 3.4 oz.

Additional screening is required so place these liquids in a separate bin at the checkpoint.

You don’t need any documentation from your doctor.

Duty Free Alcohol

Duty free liquids that you have purchased after the checkpoint can be brought on to the plane.

If you have a connecting flight you should be able to bring the alcohol through the security checkpoint if it is in tamper evident bags.

Liquid Limits For Checked Baggage

Most toiletries that are limited in carry-ons are unlimited in checked bags.

The amount of shampoo, shower gel, and sun cream you pack in your checked bag is up to you.

Aerosols and flammable liquids still need special attention, as there are additional rules for these products .

Liquor that is above 24% ABV but less than 70% ABV is restricted to 5 liters maximum because it’s somewhat flammable. Liquor over 70% ABV is banned in both carry-on and checked luggage.

Take It To The Limit… One More Time

According to the Transportation Security Administration, liquids, gels, and aerosols packed in hand luggage can only be 3.4 ounces or less when going through the airport security checkpoint.

You must pack all your liquids in one quart-size bag.

You can only have one bag per passenger.

Simple Flying

How much liquid can you take on an airplane.

The current 3-1-1 rule will change soon.

• The 3-1-1 liquid rule applies to carry-ons: each liquid container must be below 3.4 ounces, and each traveler is allowed a 1-quart-sized plastic bag, or below 1 liter in most other countries.
• Check the liquid rules when traveling internationally, as regulations vary by country.
• New 3D scanners at airports will see the easing of liquid rules and quicker security checks.

Air travel can be confusing when it comes to what is allowed in the cabin and what can be checked. Many items are prohibited and restricted due to safety and practicality considerations, and those rules have only become stricter since 9/11. It needs to be clarified as airports and countries often have variations in the rules.

However, with some welcoming news, we could see relaxation in the rules coming for the travelers . We will review the existing liquid rules worldwide and what is and could be changing in the future.

The 3-1-1 liquid rule

The 3-1-1 liquid rule is the standard for traveling in the United States. The 3 refers to a 3.4 ounce limit for each container, and the 1s refer to one plastic bag and one bag per person, respectively. For carry-ons, this is the official liquid rule according to TSA :

"Each passenger may carry liquids, gels, and aerosols in travel-sized containers that are 3.4 ounces or 100 milliliters.' The total amount of containers is limited to 'one quart-size bag."

Most countries around the world follow similar rules, with 100 milliliters being the limit for each liquid container. However, the total limit in the EU, Canada, and several other countries is one liter rather than a quart-sized bag.

For checked luggage, the rules are much more relaxed. There is generally no limit to the size or the total amount of liquid, but some hazardous liquids are prohibited. When traveling internationally, customs rules that often set limits on undeclared products need to be followed.

“Containers larger than 100 milliliters or 100 grams, even if only partially filled and whether they are opened or unopened, containing liquids, aerosols or gels are not allowed through the international security screening point.”

There are certain exceptions to the carry-on rules. Generally, liquids that fall under the ‘medically necessary’ category, including medication and prescriptions, are allowed onboard. Exceptions also include infant formula and baby food. Another instance where more than 3.4 ounces is permitted is when live fish is carried onboard in a clear container.

Since the COVID-19 pandemic, TSA and transport authorities from other countries have made another exemption for hand sanitizers. They can be larger than 3.4 ounces but need less than 12 ounces or roughly 350 milliliters.

For medical and scientific personnel, non-infectious specimens in solutions can also exceed the limit. A set of instructions needs to be followed, which can be found here . Each country and airport also differ slightly on the exemptions to the liquid rule. An example is the exception given to COVID test kits in Canada, and it is recommended to consult an airport-specific source before traveling.

Why is there a liquid rule?

Today's liquid rules known worldwide were introduced in 2006 due to suspicion of terrorism. The security of air travel was already heightened at the time but was taken a step further due to a terrorist plot in the UK, sometimes known as the 2006 transatlantic aircraft plot.

In August 2006, the British police arrested individuals who had been producing liquid bombs and explosives and plotting a terrorist attack on flights departing London Heathrow to North America. The operation saw individuals under police surveillance arrested on August 9th in the UK.

From August 9th until mid-August, British and American airports operated under extraordinary security. Most flights were canceled in the UK on August 9th, and when limited operations resumed, no carry-on except boarding passes and wallets were allowed.

In fact, liquid was not allowed onboard airplanes until August 13th in the US and until November of that year in the UK. Since then, the amount has been limited to 100 milliliters with a limited total allowance.

Changes are coming

With new technologies, the liquid rules will become a thing of the past in the coming years. The latest 3D scanning machines, including the C3-standard Explosive Detection System Cabin Baggage (EDS-CB), would ensure the same security standards are met while making the travel experience more efficient and smooth.

When installed at airports, the new machines will mean relaxed liquid rules for travelers and fewer steps when getting through security. Some likely results are reduced workload for security workers and shortened lines and delays at major international airports.

How Next Generation Airport Scanners Are Ending The 100ml Liquid Rule

Some airports have already relaxed the rules and made further exemptions. Amsterdam Schiphol, for example, states that liquid in containers larger than 100ml is permitted, but special checks are required. The 3D scanners at the Dutch airport have been available since 2021.

Some have gone a step further and scraped the 3-1-1 rule altogether. London City and Teesside airports in the UK have moved to a two-liter total liquid allowance with no limit on individual container size. More British airports are expected to adopt the new rule, and major changes are expected in June 2024 .

The Removal Of The 100ml Rule At UK Airports: Everything You Need To Know

In Ireland, Shannon airport scraped the rule in 2022 allowing any amount of liquid. In Spain, Madrid and Barcelona are expected to make changes to limits on carry-on liquid in the summer of 2024, while other Spanish airports, including Malaga and Palma de Mallorca, should follow going into 2025.

Elsewhere in Europe, other airports, including Geneva, Paris-Orly, Milan, and Helsinki, are trialing the new technology. The German airports of Munich and Frankfurt have also started converting their machines into 3D scanners, with the eventual rule change expected.

Here is a summary of all the major airports that have or will adopt the new liquid rules thanks to the new scanner technologies:

It is important to note that most airports trailing the 3D scanners still have the 100 ml cap or the 3-1-1 rule in place at the time of writing, and very few airports or countries have changed the official rules; travelers should check with the airport for the most up-to-date information.

In the US, TSA has not given any official details but is expected to follow the trend at some point. While there’s no timeline in place yet , the agency “anticipates the limit on liquids will be lifted in the coming years.”

The 3-1-1 Rule: Simplified

The TSA liquid limit, known as the “3-1-1 rule,” is a crucial part of airport security measures. At first glance, it might seem a bit complex, but it’s quite straightforward when broken down. Here’s the deal: you can carry liquids, gels, and aerosols in travel-size containers, but each container must not exceed 3.4 ounces or 100 milliliters. Now, where do these containers go? They should all fit comfortably in one transparent, quart-size bag. This bag acts as a visual aid for TSA officers, speeding up the screening process.

But why exactly 3.4 ounces or 100 milliliters? This specific limit is based on security research and analysis, determining that these quantities are safe for air travel and unlikely to be used for harmful purposes. It’s a balance between security and convenience, ensuring passenger safety while allowing you to carry your essential items.

So, each passenger is allowed one quart-size bag for their small containers. Think of it as your mini travel kit. This rule applies across the board, whether you’re flying domestic or international, making it a standard to remember for all your travels.

Understanding and adhering to the 3-1-1 rule is your ticket to a smoother airport experience. It not only helps you pass through security checks more quickly but also contributes to the overall safety and efficiency of airport operations. Remember, a little preparation goes a long way in ensuring a hassle-free start to your journey!

A Look at the Numbers

Statistics reveal the extent of the challenge: For example, just in the year 2019, TSA officers intercepted over 13 million prohibited items , a significant number of which were liquids over the allowed limit.

This staggering figure highlights the need for awareness among travelers about TSA regulations.

TSA Administrator’s Insight

David Pekoske , the TSA Administrator, emphasizes the importance of knowing what to pack. He stated,

“Our goal is to ensure that all passengers understand what they can and cannot bring through security checkpoints to maintain a safe traveling environment.”

This advice is key to a hassle-free journey.

Beating the System – The Clever Way

Navigating TSA rules can feel like a game of strategy, and knowing the exceptions is like having the best cards in your hand. Interestingly, the TSA makes allowances for certain items that are crucial for health and childcare. Medications, baby formula, and breast milk are among the items exempt from the standard 3-1-1 liquid limits.

Let’s dive deeper into these exemptions:

• Medications : If you’re traveling with prescription or over-the-counter medications in liquid form, they don’t have to adhere to the 3.4-ounce restriction. This is particularly important for those with medical conditions requiring regular medication. Make sure your medicines are easily identifiable and present them to TSA officers for inspection. It’s also a good idea to have a copy of your prescription or a doctor’s note, just in case.
• Baby Formula and Breast Milk : Parents traveling with infants or toddlers can breathe a sigh of relief. Baby formula, breast milk, and juice for infants or toddlers are permitted in reasonable quantities. This means you can carry what’s necessary for your journey, even if it exceeds the standard limit. The key here is to declare these items at the checkpoint. TSA officers typically screen them separately to ensure they’re safe for travel.
• Special Dietary Needs : Similarly, if you have special dietary requirements that involve liquids, such as nutritional shakes or juices for medical purposes, these are also allowed under the same guidelines as medications.

But here’s a pro tip: while these items are exempt, organizing them for easy access and quick presentation at security checks can save you time and hassle. Keep them separate from your other liquids in your carry-on , and inform the TSA officer as soon as you reach the checkpoint. This proactive approach shows that you’re well-informed and helps the TSA do its job more efficiently.

In summary, the TSA’s allowances for certain essential items demonstrate their commitment to balancing security with the practical needs of travelers. By being aware of these exceptions and preparing accordingly, you can ‘beat the system’ in the most clever and hassle-free way possible. Remember, the goal is to ensure safety while accommodating the genuine needs of passengers – a win-win for everyone involved.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

TSA Liquids Rule Explained: What Size Liquid Can You Bring on a Plane?

What you can and can’t bring on a plane, including the amount allowed, can be very confusing for even the most experienced of flyers, especially when it comes to liquids.

According to TSA regulations, you are allowed to bring liquids in containers that don’t exceed 3.4oz/100ml in your carry on.

There are also limits when liquids are packed in your checked bags, which many people are not aware of, though the limits are much greater.

What Size Liquid Can You Take on a Plane?

Carry on bags.

The TSA has a rule in place called the 3-1-1 Rule .

The 3-1-1 Rule states that “each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters .”

These containers must also fit in a 1-quart sized, resealable bag.

You are required to take this bag out of your carry on and place it in a screening bin as you go through airport security.

Note that it is the size of the container itself and not how much liquid is in the container that matters.

So, if you have a bottle that contains just 1ml of liquid inside a 4oz container, it still won’t be allowed through.

Checked Bags

Not many passengers are aware that there are restrictions on the quantity of liquids you can pack in their checked bags.

According to the TSA:

• A container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
• The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

No Differences For International Flights

Even though it may not be called the 3-1-1 rule worldwide, the rules remain the same if you’re flying internationally.

So regardless if you’re flying from or within Mexico, Canada, the UK, Europe or any other country, you are only allowed to pack liquids (as well as gels and aerosols) in containers that are no larger than 3.4oz/100ml in your carry on.

Airlines Follow TSA Regulations

All airlines follow TSA regulations .

So this means that regardless if you’re flying with Delta, Southwest, American Airlines, JetBlue, or any other regional or major air carrier worldwide, you are only allowed to bring liquids in containers that do not exceed 3.4oz/100ml in your carry on.

How to Pack Liquids for Flying

There are a few guidelines you should follow to make your next flight go as smoothly as possible.

• Make sure that no container you want to bring is no larger than 3.4oz/100ml.
• Buy travel-friendly products of your favorite products.
• If the company doesn’t sell travel-friendly sizes, buy your own 3.4oz/100ml containers and transfer the liquids into them.
• Consider packing non-liquid alternatives instead (you can bring a bar of soap on a plane on a plane , for example, with no restrictions. The same applies to sunscreen sticks ).
• Share toiletry space with your travel partner, as the 3-1-1 Rule applies to each passenger.
• Store your items in a clear bag that is no larger than 1 quart.
• Use your checked luggage for liquids in larger containers.

You Will Be Able to Bring 7-8 Bottles in Your Carry On

In total, you can take 32 ounces (or 1 quart) of liquids on a plane.

But as the containers themselves will take up space in the single quart-sized bag, you won’t be able to take a full 32 ounces of liquids in your carry on.

You will be able to bring about 25 ounces in total, in 7 or 8 travel-sized 3.4oz/100ml containers onto a plane in your carry on.

How Many Ounces in Total Can You Take On a Plane?

Carry on bags.

As just mentioned, you can bring 32 ounces (or 1 quart of liquids on a plane), though it will more likely be 25 ounces in 7-8 bottles.

If liquids are packed in your checked bags, each container must not exceed 18 ounces or 17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 70 ounces or 68 fluid ounces.

A Loophole to Bring More Than 3.4 Oz/100ml On a Plane

There is a loophole that lets you bring more than 3.4oz/100ml of liquids on a plane, though it only works with very few items and under certain circumstances.

If you are traveling with a young child or baby, you can say that the item is for them.

Of course, this will only work for bringing a water bottle on a plane and not items like alcohol, coffee or tea . 

Exceptions to the 3-1-1 Rule

There are several exceptions to the 3-1-1 Rule.

The following items, if packed in your carry on bags, are allowed to exceed 3.4 oz/100ml:

• Breast milk and formula
• Liquid medication
• Hand sanitizer
• Jumbo disinfecting wipes
• STEB items (secure, tamper-evident bags purchased at the airport)
• Cough syrup
• Gel-filled bras
• Saline solution
• Ice packs (must be frozen solid)

Liquids That Are Forbidden

There are several liquids that, even if under 3.4 oz/100ml, you are not allowed to bring on a plane in either your carry on or checked bags.

These items include:

• Most flammable liquids ( you can bring nail polish on a plane , though)
• Most toxic liquids
• Aerosols that do not qualify as toiletries
• Alcoholic Beverages over 70% ABV (140 proof)
• Insecticide
• Spray Paint
• Spray Starch
• Cooking Spray

Surprising Items That Qualify As Liquids

There are also items that you wouldn’t expect to count as liquids, but actually do.

• Peanut butter
• Hair mousse
• Snow globes

What the 3-1-1 Rule Stands For

The 3-1-1 Rule stands for 3 ounces, 1 passenger, 1 quart-sized bag.

While the limit is actually 3.4 ounces instead of 3 ounces, we guess that 3.4-1-1 Rule didn’t have the same ring to it.

Why the 3-1-1 Rule Exists

The 3-1-1 Rule exists because terrorists have previously tried to sneak liquid explosives on a plane on more than one occasion.

While the rule is frustrating, it exists for the safety of passengers.

Airline-specific carry-on luggage rules

Tsa liquid limits, how many ounces are allowed on a plane, additional tsa carry-on rules, final thoughts on tsa rules for carry-ons.

Whether you’re purposefully packing light or supplementing your checked luggage, it’s important to keep Transportation Security Administration (TSA) carry-on luggage size in mind when packing a bag and heading to the airport.

After all, not all airlines allow full-size carry-ons for free, and most have slightly different rules on carry-on bag size. Don’t get caught unaware at the gate; hefty baggage fees and inconvenience may await.

Here’s what you need to know about airline and TSA carry-on size allowances.

Airline carry-on dimensions differ depending on the carrier. When purchasing your flight, you’ll be able to see your carry-on and personal item limits.

A personal item is typically a small backpack, purse, briefcase, diaper bag, camera bag or any item of a similar size that can fit underneath the seat in front of you. A carry-on bag could be anything from a large backpack to a small rolling suitcase. But it’s less shape than size that matters, so here are carry-on luggage size restrictions for each of the major domestic airlines:

Alaska Airlines

On an Alaska Airlines flight, you can bring a carry-on and a personal item for free.

Carry-on bags are limited to 22 inches long, 14 inches wide and 9 inches high including wheels and handles. All three measurements shouldn’t add up to more than 45 inches.

For personal items, Alaska offers examples of a purse, laptop or briefcase.

Alaska doesn't list weight limits, but it says that passengers should be able to lift items that go in an overhead bin.

» Learn more: Guide to Alaska Airlines baggage and other fees

American Airlines

For an American Airlines flight, passengers get one personal item and one carry-on, no matter what type of fare is bought (elite members included).

Carry-on bags shouldn’t be larger than 22 inches long, 14 inches wide and 9 inches high including handles and wheels.

Dimensions of personal items should not exceed 18 inches long, 14 inches wide and 8 inches high.

There are no weight restrictions for carry-on luggage.

Delta Air Lines

Delta flyers are allowed one carry-on bag and one personal item.

Including wheels and handles, measurements may not exceed 22 inches long, 14 inches width and 9 inches high. The total length plus width plus height of baggage must not exceed 45 linear inches.

For personal items, Delta says size examples are purses, small backpacks and laptops.

Three places have weight limits: Singapore (7 kg, about 15.4 pounds), Beijing (10 kg, about 22 pounds) and Shanghai (10 kg, about 22 pounds).

Frontier charges for both checked luggage and carry-on bags, and the price depends on the route you fly. It also varies depending on if you buy the bags before via the web or mobile app, at the ticket desk, or the boarding gate.

Carry-on bags must weigh less than 35 pounds and must not exceed 10 inches deep, 16 inches wide and 24 inches high. Bags must fit in the overhead bins.

Checked bags must be no longer than 62 linear inches (length + width + depth) and must weigh under 40 pounds. Bags weighing more than 40 pounds will incur additional charges per bag per direction. Bags weighing 41-50 pounds will cost you $50 more and bags weighing 51-100 pounds will cost $100 more.

Personal items cannot exceed 8 inches deep, 18 inches wide and 14 inches high.

» Learn more: Frontier baggage fees: How they work

Not all JetBlue passengers are allowed the same carry-on items. Passengers who bought Basic Blue fares get one personal item (except Mosaic customers who always get a carry-on). Blue, Extra Blue, Blue Plus and Mint fares allow one carry-on and one personal item.

Including wheels and handles, length, width and height measurements may not exceed 22 inches long, 14 inches wide and 9 inches high.

Personal items can be no more than 17 inches long, 13 inches wide and 9 inches high or smaller to fit under the seat in front of you.

There are no weight limits for carry-on luggage on JetBlue.

» Learn more: Guide to JetBlue baggage, cancellation and other fees

Southwest Airlines

Southwest is known for having a generous free checked luggage allowance, but carry-on restrictions are similar to most other airlines — one personal item and one carry-on per traveler.

Carry-on measurements should not exceed 24 inches long, 16 inches wide and 10 inches high.

Personal items are limited to 18.5 inches long, 8.5 inches wide and 13.5 inches high.

Southwest doesn't list weight limits for carry-on items.

» Learn more: The guide to Southwest baggage and other fees

United Airlines

Most travelers flying with United can bring one carry-on and one personal item, but if you’re traveling on a basic economy fare, you’re allowed one personal item only (unless you’re a MileagePlus Premier Member, are traveling internationally or have a MileagePlus credit card, like the United℠ Business Card ).

Including handles and wheels, the maximum dimensions for a carry-on are 22 inches long, 14 inches wide and 9 inches high.

Personal items are limited to 17 inches long, 10 inches wide and 9 inches high.

United doesn't publish weight limits for carry-ons.

» Learn more: What you need to know about United Airlines baggage and other fees

Depending on the airline you fly with as well as how long you’re traveling for, you might wonder whether you’re better off traveling with a checked bag rather than a carry-on . This can be especially relevant if you’ve got some liquids with you that exceed the TSA carry-on liquid limits.

Before you even make it to your departure gate, you have to clear a TSA checkpoint. This means you must adhere to the TSA liquid limit in order to make it through security.

Containers that are 3.4 ounces or less are allowed, but there are other rules to keep in mind as well.

Carry-on liquid limit

The TSA liquid rule — also known as the 3-1-1 rule (3 ounces, 1 bag per 1 person) — is straightforward: "You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item." Any liquids in larger containers will have to go into checked baggage (and are subject to overweight fees).

A basic clear, zip-top container qualifies as an eligible quart-size bag for passing through security.

The easiest way to manage the amount of fluids in your carry-on is to start with containers that are no larger than 3.4 ounces or 100 milliliters and your quart-sized bag.

The maximum carry-on liquid size and amount will depend on how much you can fit into your single quart-sized bag.

3-1-1 liquids rule exemptions

The 3-1-1 liquid rule has several exceptions if you're traveling with certain liquid medicines or baby food.

TSA allows larger amounts of certain medically necessary liquids, gels and aerosols in "reasonable quantities" for your trip. The amount allowed is not stated.

The only catch? You must declare the medication to TSA officers at the checkpoint for inspection, alongside any accessories associated with your medicine, such as freezer packs or syringes.

Labeling your medical items can help facilitate the screening process.

Formula and breast milk are considered medically necessary liquids, and thus exempt from the carry-on liquid limit. Water and juice for babies is also allowed in quantities greater than 3.4 ounces or 100 milliliters.

These child and infant nourishment items are allowed in carry-on baggage and do not need to fit within a quart-sized bag. You may also bring teethers that are gel- or liquid-filled and canned/jarred/processed baby food in your carry-on baggage.

» Learn more: 7 ways to avoid paying bag fees

Duty-free liquids

The final exemption to TSA liquid limits apply to duty-free liquids purchased during inbound international flights. It's important that these bags are secure and temper evident and stored in a transparent bag.

Be sure to keep the item's original receipt handy in case a TSA officer asks to see it.

» Learn more: Can you bring food through TSA?

The only flammables allowed in a carry-on are cigars, cigarettes, disposable and Zippo lighters, and dry batteries (like AAs or AAAs).

Camping and sports equipment

You can carry-on an air mattress with a built-in pump (by following special instructions), antlers, basketballs, footballs, baseballs, soccer balls, bike chains and bike pumps. Bicycle allowances vary by airline, but baseball bats, bear spray and bear bangers are never allowed — nor is aerosol insecticide.

Other items

There are some banned items, including knives, firearms and box cutters. A full list of which can be found on TSA’s website .

Still not sure if something you plan to carry-on is restricted? Send a photo to AskTSA on Twitter or Facebook Messenger to find out.

No matter which airline you fly with, first make sure you know what size carry-on you’re allowed to bring onboard and are familiar with (and prepared for) TSA’s carry-on restrictions, too. Then, you can expect a smoother and less stressful airport and airliner experience.

Guide to TSA Carry-On Liquid Restrictions

Guide to T SA Carry-On Liquid Restrictions is key to smooth air travel. So, let’s simplify these confusing rules, uncover what to do and avoid, and share some handy tips to help you sail through airport security with liquids.

Essentials of Liquids Rule

To start, let’s get a grip on the core basics of TSA’s liquids rule:

• 3-1-1 Rule: This primary rule permits travelers to carry liquids in containers up to 3.4 ounces (100 milliliters), tucked in a quart-sized, transparent, ziplock plastic bag. Each traveler gets one bag.
• Container Size : Beware of your container size. Anything beyond 3.4 ounces should be in your checked baggage, following the liquids rule.
• Medicines and Baby Stuff : Exceptions are given for essential liquids like medicines and baby formula. Keep these handy for review.

TSA Carry-On Liquid Restrictions

• Liquids: Pack toiletries like shampoo, conditioner, and lotion but stick to 3.4 ounces or less.
• Gels and Aerosols: Just like liquids, limit hair gel, toothpaste, and gel deodorants to follow the 3-1-1 rule.
• Drinks: The 3.4-ounce rule applies to beverages too. You might want to buy drinks after security.

Exceptions to the Rule

• Medications: The 3-1-1 rule does not apply to prescription and over-the-counter drugs. But remember, clearly label them for inspection.
• Baby essentials: Baby formula, breast milk, and baby food in reasonable amounts are okay. Remember, with these items, expect more screening.
• Duty-Free Buys: Liquids from the duty-free zone are permitted post-security, just show your receipt. Mind restrictions for connecting flights.

Smarter Ways to Pack

Want to ace the liquids rule? Here’s how to pack:

• Get Travel-Size Bottles: Buy smaller toiletries or place your loved items into mini, TSA-okayed bottles to fit the 3.4-ounce limit.
• Pick the Quart-Sized Bag: Have your clear, quart-sized bag within reach in your carry-on for a faster security check.
• Merge Items: Group together several small things in a single bag. This will save room and follow the liquids rule while keeping necessary items.

Guide to Security Checks

Kickstart your trip smoothly by mastering the art of liquid rules in security checks:

• Quart-Sized Bag Action: Your liquids should be in a quart-sized bag, placed separately in a bin during X-ray checks.
• Speak Up About Medication: If you have medications, alert the security crew. They might need delicate handling.
• Stay in the Loop: TSA guidelines can change. Stay updated to match their latest rules.

Blunders to Evade

Even frequent flyers can slip. Here’s what to watch out for:

• Missing Quart-Sized Bag: Remember to prepare your quart-sized bag. It could save time.
• Overlooking Duty-Free Caps: Bought duty-free liquids? Know the limit, especially for connecting flights.
• Misjudging the Liquid Types: Gels, aerosols, or liquids? Each has unique rules. Brushing up the facts could save you from shocks at the security gate.

Ending Notes

Mastering TSA Carry-On Liquid Restrictions is like learning an art – it’s all about preparation and knowledge. Get to know the rules. Learn what you can and can’t pack. Discover smart ways to pack. This ensures your journey through airport security is hassle-free. So, be smart, pack right and let TSA’s liquids rule be a natural part of your travelling habit.

Understanding Travel Ounce Restrictions: What You Need To Know

• Category United States

Traveling can prove to be an adventure of a lifetime. Exploring new cultures, trying out exotic cuisines, and immersing oneself in unfamiliar surroundings can make for memories that last a lifetime. However, when it comes to packing for a trip, one is often faced with a conundrum - how to fit everything into the limited space and weight restrictions of an ounce. Whether it's the challenge of streamlining one's wardrobe or deciding which toiletries are essential, navigating travel ounce restrictions can be a puzzle that tests the savvy of even the most seasoned traveler. In this article, we will explore the art of packing efficiently and making the most of the precious space available. So tighten your seatbelts and get ready for a crash course in travel ounce restrictions!

What You'll Learn

What are travel ounce restrictions, why do some countries impose travel ounce restrictions, how do travel ounce restrictions differ from other types of travel restrictions, what are some common examples of travel ounce restrictions, how can travelers navigate travel ounce restrictions to ensure a smooth journey.

Travel ounce restrictions refer to the limitations on the amount of liquids, gels, and aerosols that can be brought in carry-on luggage when traveling by air. These restrictions were put in place by aviation authorities around the world as a security measure to prevent the smuggling of dangerous substances and reduce the risk of terrorist attacks.

The most common ounce restriction is the 3-1-1 rule, which was implemented by the Transportation Security Administration (TSA) in the United States. According to this rule, passengers are allowed to bring liquids, gels, and aerosols in containers that are 3.4 ounces (100 milliliters) or less in their carry-on bags. These containers must be placed in a clear, quart-sized plastic bag, with only one bag allowed per passenger.

The 3-1-1 rule applies to a wide range of items, including toiletries such as shampoo, conditioner, toothpaste, and deodorant, as well as cosmetics, perfumes, and certain food items. It is important to note that the restriction applies to the container size, not the amount of liquid inside. So even if a bottle contains less than 3.4 ounces of liquid, it still cannot be brought in the carry-on bag if the container itself is larger than the allowed size.

There are a few exceptions to the 3-1-1 rule. Prescription medications and baby formula are allowed in larger quantities, as long as they are declared to the security officers at the checkpoint. Additionally, duty-free liquids purchased at the airport or onboard the aircraft, as long as they are properly sealed in a Secure Tamper-Evident Bag (STEB), are also allowed.

It is important for travelers to follow these ounce restrictions to avoid delays and the confiscation of their belongings at the security checkpoint. Many airports provide clear plastic bags for passengers to transfer their liquids into if they do not have one. It is recommended to pack all liquids in the carry-on bag in an easily accessible manner, as they need to be screened separately during the security screening process.

To comply with the ounce restrictions, travelers have a few options. They can either purchase travel-sized toiletries that comply with the 3.4 ounces limit or transfer the liquids into smaller travel-sized containers. Many popular brands offer travel-sized versions of their products, making it convenient for travelers to comply with the restrictions. Alternatively, travelers can pack their liquids in their checked luggage, as there are no restrictions on the amount of liquids that can be packed in this type of baggage.

In conclusion, travel ounce restrictions, such as the 3-1-1 rule, are in place to ensure the safety of air travel by limiting the amount of liquids, gels, and aerosols that can be brought in carry-on luggage. Passengers must adhere to these restrictions by packing their liquids in containers that are 3.4 ounces or less and placing them in a clear, quart-sized plastic bag. By following these rules, travelers can help maintain the security and efficiency of the airport screening process.

The Latest Updates on Nevada Air Travel Restrictions: What You Need to Know

In recent times, we have witnessed numerous countries imposing travel ounce restrictions. These restrictions may vary from complete travel bans to mandatory quarantine measures for travelers arriving from certain regions. But what is the reasoning behind these measures? In this article, we will explore the rationales behind countries imposing travel ounce restrictions, utilizing both scientific research and real-world examples.

Protecting Public Health:

One of the primary reasons for countries to impose travel ounce restrictions is to protect public health. During a pandemic or disease outbreak, such as the COVID-19 pandemic, travel can play a significant role in spreading the disease across borders. By imposing restrictions on travel, countries aim to minimize the risk of imported cases and potential outbreaks within their territories.

Scientific research has shown that travel plays a crucial role in COVID-19 transmission. A study published in The Lancet found that the introduction of travel restrictions during the early stages of the pandemic helped reduce the transmission rate in affected regions. By limiting travel, countries can slow down the spread of the virus and buy time to implement necessary public health measures, such as testing, contact tracing, and vaccination.

Controlling Variant Spread:

Travel ounce restrictions also enable countries to control the spread of new variants of the virus. Many variants of concern have emerged during the COVID-19 pandemic, with some being more transmissible or resistant to vaccines. By restricting travel from regions with high variant prevalence, countries can limit the introduction of these variants and reduce the risk of their further spread within their populations.

For example, in early 2021, the United Kingdom implemented strict travel bans and quarantine measures for travelers coming from countries with high variant prevalence, such as Brazil and South Africa. This decision was based on scientific evidence suggesting that these variants had the potential to compromise vaccine efficacy and lead to increased transmission. By taking proactive measures, the UK aimed to protect its population from the potential risks associated with these variants.

Containing Overwhelmed Healthcare Systems:

Another reason for implementing travel ounce restrictions is to prevent overwhelming healthcare systems. During a pandemic or a surge in cases, healthcare systems may experience a significant strain, with limited capacity to handle a large number of patients. By restricting travel, countries can reduce the influx of cases and prevent their healthcare systems from becoming overwhelmed.

This was seen during the initial stages of the COVID-19 pandemic when several countries, including Italy and Spain, faced a rapid increase in cases. These countries implemented strict travel bans and lockdown measures to lessen the burden on their healthcare systems and ensure that adequate resources were available for those in need.

In conclusion, countries impose travel ounce restrictions for various reasons, including protecting public health, controlling the spread of variants, and preventing healthcare system overload. Scientific research and real-world examples have shown that these measures can be effective in mitigating the impact of pandemics and disease outbreaks. While travel ounce restrictions may inconvenience individuals, they are implemented with the aim of safeguarding public health and preventing the further spread of infectious diseases.

What Is the Duration of Europe's Travel Restrictions During the COVID-19 Pandemic?

Travel restrictions have become an essential part of the global response to the COVID-19 pandemic. These restrictions aim to reduce the spread of the virus and protect public health. One type of travel restriction that has been implemented by many countries is the ounce restrictions for travelers. Unlike other types of travel restrictions, ounce restrictions specifically target the amount of luggage and belongings that travelers can bring with them.

Ounce restrictions, also known as baggage restrictions, are limits imposed on the weight of luggage that travelers can bring on a trip. They are usually set by airlines and vary depending on the ticket type and destination. These restrictions apply to both checked baggage and carry-on baggage.

One key difference between ounce restrictions and other types of travel restrictions is their focus on the physical weight of belongings. Other travel restrictions, such as visa requirements or quarantine measures, are concerned with the personal characteristics or health status of travelers. Ounce restrictions, on the other hand, are more practical and objective. They are based solely on the weight capacity of the airline and the aircraft.

To comply with ounce restrictions, travelers must carefully pack their belongings and ensure that they do not exceed the weight limit imposed by the airline. This can be done by weighing the luggage before the trip and avoiding unnecessary items. It is also important to consider the weight of carry-on baggage, as this is often subject to ounce restrictions as well.

Unlike other types of travel restrictions, ounce restrictions can directly impact the travel experience. Exceeding the weight limit may result in additional fees or the need to leave belongings behind. This can be particularly challenging for travelers who have brought souvenirs or other items from their destination. It is therefore crucial for travelers to be aware of the ounce restrictions before packing and to plan accordingly.

There are several reasons why airlines enforce ounce restrictions. Firstly, excess baggage can pose safety risks. Overloaded aircraft may have difficulty taking off and landing, and the weight distribution of the plane can be affected. Secondly, ounce restrictions help airlines manage their limited cargo space. By enforcing weight limits, airlines can ensure that all passengers have enough space for their luggage. Finally, ounce restrictions also aim to restrict the transportation of potentially dangerous goods, such as hazardous materials.

In conclusion, ounce restrictions differ from other types of travel restrictions in that they specifically target the weight of luggage that travelers can bring on a trip. They are practical and objective, focusing on the weight capacity of the airline and the aircraft. Ounce restrictions directly impact the travel experience and require travelers to carefully pack their belongings to avoid exceeding the weight limit. By enforcing ounce restrictions, airlines prioritize safety, manage cargo space, and restrict the transportation of potentially dangerous goods.

Pennsylvania Travel Restrictions: A Guide by CDC

As avid travelers, it is important to understand the restrictions that can often be placed on the weight of our luggage. Many airlines and transportation companies have specific restrictions on how much luggage passengers can bring with them. One common restriction is the limit on the weight of each bag or suitcase, sometimes referred to as travel ounce restrictions.

These restrictions are in place for a number of reasons. Firstly, they ensure that passengers are not overloading the aircraft or transportation vehicle, which can affect fuel efficiency and overall safety. Additionally, these restrictions help maintain fair and consistent pricing, as heavier bags may require more manpower or special handling.

The specific ounce restrictions can vary depending on the airline or transportation company, as well as the class of service and destination. However, there are some general examples that can help give you an idea of what to expect.

For domestic flights within the United States, most airlines have a standard weight limit of 50 pounds (approximately 22.7 kilograms) per checked bag. If your bag exceeds this limit, you may be charged an overweight fee or be asked to repack your belongings into multiple bags. For carry-on luggage, the weight limit is typically around 40 pounds (approximately 18.1 kilograms), although it is always best to check with your specific airline for their exact regulations.

International flights often have higher weight limits, as passengers may need to bring more belongings for longer trips. However, it is important to note that each airline has its own policies, so it is best to consult their website or contact their customer service for up-to-date information. Some international flights may allow a checked bag weight of up to 70 pounds (approximately 31.8 kilograms), while others may have lower limits.

It is also worth mentioning that some airlines have a limit on the total number of checked bags that each passenger is allowed. This can range from one to three bags, depending on the airline and travel class. Exceeding this limit may result in additional fees or the need to ship your excess luggage separately.

In addition to weight restrictions, there may also be restrictions on the size or dimensions of your luggage. Most airlines have a maximum linear dimension of around 62 inches (length + width + height) for checked bags, and around 45 inches for carry-on bags. Again, it is important to check with your specific airline for their exact requirements.

To avoid any surprises or additional fees, it is always best to weigh your luggage at home before heading to the airport. This will give you a clear understanding of whether or not your bag is within the weight limit. If you find that your bag is overweight, consider removing non-essential items or redistributing them into your other bags.

In conclusion, travel ounce restrictions are common in the travel industry and are in place to ensure safety and fair pricing. Most airlines have a weight limit of around 50 pounds for checked bags on domestic flights, and may have higher limits for international flights. It is important to check with your specific airline for their exact regulations and to weigh your luggage before heading to the airport. By doing so, you can ensure a smooth and stress-free travel experience.

Exploring Travel Restrictions to Switzerland: What You Need to Know

Traveling can be a wonderful experience, whether you are going on a vacation or flying for business. However, one aspect that can cause headaches for many travelers is dealing with travel ounce restrictions. Airlines have strict rules when it comes to the size and weight of your luggage, and navigating these restrictions can be tricky. To ensure a smooth journey, there are a few steps that travelers can take.

• Familiarize yourself with airline policies: Before you pack your bags, it is important to familiarize yourself with the specific ounce restrictions of the airline you are flying with. Different airlines have different rules, so it is crucial to check their website or contact customer service to understand the limitations.
• Invest in a lightweight suitcase: One way to ensure that your luggage meets the ounce restrictions is to invest in a lightweight suitcase. Many manufacturers now offer suitcases that are lightweight, yet still durable. Choosing a lightweight option will allow you to pack more items without exceeding the weight limit.
• Use a digital luggage scale: To avoid any surprises at the airport, it is beneficial to invest in a digital luggage scale. This will allow you to weigh your luggage before heading to the airport, ensuring that it falls within the allowed weight limits. By using a digital luggage scale at home, you can rearrange or remove items as necessary to avoid any extra fees or complications at the airport.
• Pack efficiently: Packing efficiently is key to navigating travel ounce restrictions. To make the most of the limited space, roll your clothes instead of folding them, as this can save valuable space in your suitcase. Utilize packing cubes or compression bags to condense your belongings and maximize space. Pack versatile clothing that can be mixed and matched to create multiple outfits, reducing the need for excess items.
• Wear your heaviest items: If you find yourself struggling to fit everything within the weight limits, consider wearing your heaviest or bulkiest items instead of packing them. This can include wearing your boots, jacket, or any other items that might add unnecessary weight to your luggage. Although this may not help with size restrictions, it can greatly reduce the weight of your suitcase.
• Utilize personal item allowances: Most airlines allow passengers to bring a personal item in addition to their carry-on bag. Take advantage of this by choosing a carry-on bag that can fit under the seat in front of you and pack some of your smaller, heavier items in it. This will not only help you navigate the weight restrictions but also maximize the space in your carry-on bag.
• Consider shipping items ahead of time: If you have items that are difficult to fit within the ounce restrictions, consider shipping them ahead of time to your destination. This can be especially useful for large or bulky items that would take up a significant amount of space and weight in your luggage.

By following these steps, travelers can navigate travel ounce restrictions and ensure a smooth journey. By familiarizing yourself with airline policies, investing in a lightweight suitcase, using a digital luggage scale, packing efficiently, wearing your heaviest items, utilizing personal item allowances, and considering shipping items ahead of time, you can avoid any last-minute surprises and enjoy your trip to the fullest. Remember to always check the specific rules and restrictions of the airline you are flying with to ensure a hassle-free travel experience.

Frequently asked questions.

Travel ounce restrictions refer to the limitations on the amount of liquid, gel, or aerosol substances that travellers are allowed to bring in their carry-on luggage or through airport security checkpoints. These restrictions were implemented in response to security concerns regarding the potential threat of liquid explosives.

The maximum volume allowed for liquids in carry-on luggage is 3.4 ounces (100 milliliters) per container. These containers must be placed in a clear, quart-sized plastic bag and each passenger is limited to one bag. Any containers that exceed this limit must be packed in checked luggage.

Yes, there are a few exceptions to the travel ounce restrictions. Medically necessary liquids and baby food/formula are allowed in larger quantities, but they must be declared to security personnel and may be subject to additional screening. Additionally, duty-free liquids purchased after the security checkpoint are allowed and do not count towards the ounce restrictions.

The ounce restrictions on liquids were implemented as a security measure to mitigate the risk of liquid explosives being brought on board airplanes. By limiting the quantity of liquids that can be carried in carry-on luggage, it reduces the potential for individuals to create or smuggle dangerous substances onto an aircraft. These restrictions are in place to ensure the safety and security of air travel for all passengers.

The U.K. Ended Its Travel-Size Liquid Rule for Carry-Ons—Will the U.S. Do the Same?

By Jessica Puckett

Passing through airport security in the U.K. is about to get easier and more streamlined, as U.K. officials announced that the rule mandating liquids in carry-on bags be 100ml (3.4 ounces) or less will no longer be enforced, starting in June 2024. 

When the rule ends, passengers will be able to carry-on liquids measuring up to two liters in volume, the BBC reports . Additionally, passengers will no longer need to remove electronics from bags, such as laptops. Previously, major airports in the U.K., such as London Heathrow, were known for their stringent enforcements of the liquid rules.

In the U.S., similar policies are still in effect at airports around the country, with the TSA enforcing its so-called “ 3-1-1 ” liquid rule for carry-on bags: all liquids must be 3.4 ounces or less and fit in a single, one-quart clear bag. (Though there are  some exceptions to those rules.)

The more relaxed screening policies in the U.K. are possible thanks to new X-ray scanners that use computed tomography (CT) technology to produce more detailed, 3D images of luggage contents. (The technology is similar to a CT scan you might get at a hospital.) Most airports in the U.K. will need to upgrade their X-ray machines to the newer high-tech versions by June 2024. 

The same enhanced CT technology has been in use at U.S. airports for several years now, with the TSA rapidly expanding the scanners to dozens of airports nationwide. As of May 2022, the agency said it had deployed at least 402 CT units to 163 airports around the country. Over the summer, officials installed more of the scanners at additional airport checkpoints in anticipation of an uptick in air travelers, including at Billings Logan International Airport in Montana , Albany International Airport in New York, Buffalo Niagara International Airport in New York, Cincinnati/Northern Kentucky International Airport and Raleigh-Durham International Airport in North Carolina, the TSA  said in a release . 

With that in mind, will the TSA follow the U.K.’s lead and ditch its rules for carry-on liquids? Currently at U.S. security checkpoints with CT scanners, passengers already have somewhat more relaxed screening rules, as they aren’t required to remove their travel-size liquids, electronics, or food from their carry-on bags, according to the TSA. That was a precursor step to the new U.K. policy at  London City airport , which received CT scanners in November 2022 and announced that passengers no longer had to remove any items from their bags. 

But some industry analysts say scanning equipment is only one piece of the puzzle . “I believe that TSA and other aviation security organizations will study the results from the UK’s decision closely and carefully,” says Henry Harteveldt, an aviation expert and president of Atmosphere Research. “If behavioral profiling and other similar tools allow security organizations to potentially detect people who may pose a danger to airline crews and passengers, it may help reduce the need for measures such as the 100ml limit on liquids and the TSA’s 3-1-1 policy.”

Indeed, it seems U.S. officials plan to take it slow when considering any changes to the current TSA 3.4-oz liquid rule, which has been the international standard since it was implemented in 2006. “Computed Tomography technology produces 3-D images that can be rotated and combined with advanced detection algorithms to produce a substantial improvement in security screening,” Robert Carter Langston, TSA's press secretary, said in an emailed statement. “While we have them deployed at more checkpoints, we are years away from announcing a change to the current liquids rule.” 

Although U.S. passengers still need to pack travel-size liquids for the time being, that doesn’t mean that the security checkpoint hasn’t been seeing other improvements. Aside from rolling out more CT scanners, TSA has been deploying credential authentication technology: new ID scanners that don’t require passengers to show their boarding passes . Earlier in 2022, the agency also began accepting digital IDs from the Apple Wallet app at certain airports and testing an expansion of facial recognition to whisk travelers through even faster.

The best packing cubes to save space and keep you organized

These travel cubes will keep your suitcase in order, whether you’re going on a short getaway or a round-the-world adventure.

Whether you’re packing for a weekend getaway or planning an around-the-world adventure, packing cubes can help streamline the packing process. Packing cubes are bags that come in different sizes in a set. They can help organize clothing and save room in your suitcase. Frequent traveler Kayli King uses packing bags daily to keep clothes organized in her van while traveling. “Honestly, after traveling so long, I can’t imagine not using them,” she says.  

After talking to King, we compared packing bags, looking for durable travel cubes with functional designs and a wide variety of sizes. Our top overall pick is the Gonex Compression Packing Cubes. Compression zippers, handles, and a low price tag make this set the best all around.

Our picks for the best packing cubes for travel

The best packing cubes for travel, best overall: gonex compression packing cubes.

Buy it now on   Amazon

Why we like it:   The Gonex Compression Packing Cubes are our choice for the best overall packing cubes. Despite being one of the more affordable travel cube sets on this list, these compression bags have plenty of features, including ripstop nylon, reinforced seams, and handles. They compress via double zippers that pull the edges of the travel packing bag together. The packing cubes can hold everything from socks to jackets and are designed to fit together like puzzle pieces. They’re also available in over 10 colors.

Keep in mind:   These packing cubes unzip only halfway, so you have to stuff your clothes inside rather than lay them flat. Some reviewers note that the compression zippers are difficult for people with arthritis or reduced mobility.

Product details: Size: 4-piece set: 9.8 x 7.5 x 3.54 inches (small), 11.8 x 8.9 x 3.54 inches (medium), 14.5 x 10.6 x 3.54 inches (large), and 17.3 x 13 x 3.54 inches (extra large) | Material:   Ripstop nylon | Weight: 12 ounces (set)  

Best for traveling light: Eagle Creek Pack-It Isolate Cube Set  

Buy it now at   Backcountry

Why we like it: At 4.2 ounces, the Eagle Creek Pack-It Isolate Cube Set is half the weight of other packing cubes on this list, but they’re far from flimsy. They’re made of ripstop polyester and have “self-repairing” zippers—if a gap opens in the chain, you can slide one of the zippers over it to close it. Eagle Creek also offers a warranty that covers fabric tears and zippers. Because they’re lightweight and sturdy, these travel cubes are great for hikers and campers who want to organize their backpacks.  

Keep in mind: The set includes only three smaller-sized travel cubes. While great for backpacks and carry-ons, you may want bigger packing cubes for checked luggage.

Product details: Size:   3-piece set: 4.5 x 7.5 x 2.5 inches (extra small), 7.25 x 10 x 3.25 inches (small), and 10 x 14.25 x 3.25 inches (medium) | Material:   Ripstop polyester | Weight:   4.2 ounces (set)  

Best for overpackers: REI Co-op Expandable Packing Cube Set

Buy it now at   REI

Why we like it:   The packing cubes in the REI Co-op Expandable Packing Cube Set are the opposite of compression bags. Each cube has a second zipper that, when unzipped, increases its width to six inches—double the size of other packing bags on this list. They’re designed to last with ripstop polyester treated with a durable water-repellent (DWR) finish. The packing cubes also meet the Bluesign criteria, the highest environmental standard for sustainable textile manufacturing.

Keep in mind:   REI Co-op recently updated its packing cubes, and some buyers believe the quality has suffered as a result. Third-party reviews mention thin material, unreinforced zippers, and mesh that snags.

Product details: Size:   3-piece set: 8 x 6 x 3 inches (small), 12 x 8 x 3 inches (medium), and 14.5 x 10.5 x 3 inches (large) | Material:   Ripstop nylon, polyester mesh | Weight: 8.3 ounce (set)  

Best upcycled option: Cotopaxi Cubo Packing Cube Bundle

Why we like it:   The brightly colored Cotopaxi Cubo Packing Cube Bundle is an upcycled option you can feel good about. The packing bags are made of 100-percent repurposed nylon and mesh. Kayli King likes that the mesh panels allow your things to air out and that you can hang them up by their handles.

Cotopaxi’s sustainability initiatives extend beyond its packing cubes. The company says that 94 percent of its products use repurposed, recycled, or responsible materials. They also offer programs to repair items and trade them in to avoid landfills.

Keep in mind:   Despite its competitive price, this bundle comes with only three packing cubes. The size range is small compared to other packing cube sets. However, King prefers this set for longer trips.

Product details: Size: 3-piece set: 7 x 8 x 2 inches (2-liter bag), 6 x 11.5 x 3 inches (3-liter bag), 10 x 11.5 x 5 inches (10-liter bag) | Material:   100 percent repurposed nylon and mesh | Weight: 9 ounces (set)

Best style: Calpak Packing Cubes Set

Buy it now at   Calpak

Why we like it:   While many packing cubes seem to favor function over fashion, the Calpak Packing Cubes Set balances both. The packing bags come in over 20 colors, with patterns like “cheetah” and “lime viper.” They’re durable, with thick polyester sides and mesh covers that let you see inside. Each packing cube has a zippered pocket for smaller essentials and an ID tag to write down the contents. If five travel cubes aren’t enough, you can buy additional Calpak travel organizers, like shoe bags and laptop totes.

Keep in mind:   The Calpak Packing Cube set is by far the heaviest and most expensive option on this list. You may want lighter packing cubes if you travel with just a carry-on or are concerned about overweight luggage.

Product details: Size:   5-piece set: 13 x 10 x 1.5 inches (envelope), 12 x 8.8 x 3 inches (small x 2), 5 x 11 x 3 inches (medium), 17 x 12 x 3 inches (large) | Material: Polyester and mesh | Weight: 1 pound, 12.8 ounces (set)  

Best set: Tripped Checked Bag Set

Why we like it:   The Tripped Checked Bag Set has a travel cube for almost every packing need. The set includes seven packing bags, including two extra large sizes, a slim cube, a shoe bag, and a roll-top laundry bag. Mix and match the travel cubes to fit your suitcase and packing needs. Most of the packing cubes in the Checked Bag Set also have a compression feature. Plus, they come in a wide range of colors and an illustrated set featuring national parks.  

Keep in mind:   While the packing cubes are made from a ripstop blend, reviewers mention that the material and stitching feel thin and flimsy. Some of the travel cubes don’t unzip all the way, making packing more difficult.

Product details: Size: 6-piece set: 12.5 x 6.5 x 6.5 inches (shoe bag), 12.5 x 4.5 x 3 inches (slim cube), 21 x 11.5 x 0.1 inches (laundry bag), 10 x 7 x 4 inches (small), 14 x 10 x 4 inches (large), 16 x 12 x 4 inches (extra large x 2) | Material:   Ripstop nylon-polyester blend | Weight:   15.5 ounces (set)  

Best budget: Veken 6 Set Packing Cubes

Why we like it: The Veken 6 Set Packing Cubes come with six packing cubes, including a laundry bag and a shoe bag. They cost less than half the price of most other packing bag sets on this list. The low price doesn’t mean low quality, though. The Veken 6 Set Packing Cubes are made of thick polyester, with sturdy zippers and mesh panels to help keep clothes fresh. Plus, they come in 12 colors.  

Keep in mind: The laundry and shoe bags are small. The polyester is not ripstop and can melt if dried on high heat.

Product details: Size: 6-piece set: 4.7 x 17 inches (shoe bag), 14 x 20 inches (laundry bag), 11 x 6.75 x 4 inches (small), 13.75 x 9.75 x 4 inches (medium), 13.75 x 12.75 x 4 inches (large), 17.5 x 12.15 x 5 inches (extra large) | Material:   Polyester | Weight:   10.4 ounces (set)  

How we chose the best travel packing cubes

We weighed the following qualities when curating the best packing cubes:

Third-party reviews:   We considered reviews from sources other than company websites and spoke with seasoned travelers to find out what they liked.  

Brand reputation: Anything you use for traveling should be functional, long-lasting, and, preferably, good for the planet. We looked for brands that value high-quality gear and sustainability.

Quality of material:   We chose travel cubes that were made to last, with durable materials like ripstop nylon and polyester, reinforced seams, and strong zippers.

Size range: Different-sized packing bags make for an easier packing experience. We chose packing cube sets in a range of sizes, from extra small to extra large.

Compression options: Some packing cube brands offer compression bags, which can be a nice feature if you’re tight on space.  

Tips for buying packing bags

Here’s what to consider when picking your own packing cubes:

Brand reputation  

Choose a trusted brand with a proven reputation. Brands with zipper and fabric warranties or repair programs will also help you get as many vacations as possible with your travel organizers.

If you only use carry-ons or smaller luggage, choose a packing cube set with fewer, smaller travel cubes. If you prefer to use checked luggage, go for a packing cube set with more travel cubes and bigger sizes.  

If you travel with just a carry-on or want to use packing cubes for hiking, choose an ultralight packing cube set. Every ounce counts when packing light, and some travel cube sets are nearly 1.5 pounds lighter than others.

Packing cubes are typically made of polyester or nylon, both strong synthetic fabrics. If you need something even more durable, look for ripstop nylon or polyester, which has extra threads to prevent tears from becoming bigger.

Some brands offer compression bags, which can save space. However, King finds that compressed bags can be awkwardly shaped, making them harder to fit together in your suitcase. If you are a heavy packer, travel cubes for shoes or laundry can help keep the rest of your luggage clean.
