Carry-on luggage size and weight limits (2024).

Just like checked bags, carry-on luggage size restrictions can vary by airline.

Carry-on Luggage Sizes by Airline

If you're traveling with carry-on luggage and/or a personal item, you'll need to adhere to size restrictions in the same way you do with checked bags . These rules include the dimensions of your carry-on bag and, in some scenarios, even the weight.

What size luggage is a carry-on?

While carry-on luggage sizes can vary by airline, several major carriers go by these dimensions.

Airlines calculate carry-on luggage size measurements using two methods:

• Height by width by depth:  Most – but not all – airlines measure bags by inches or centimeters using this formula: height by width by depth, such as 22 x 14 x 9 inches. (Note: The dimensions listed below, which are given according to that formula, may differ slightly from the way each individual airline formats its size requirements.)
• Linear inches:  A few airlines have linear inch restrictions for carry-on baggage, meaning the airline gives one number for the total of all three dimensions. As long as the combined height, width and depth don't exceed that number, you're in the clear.

Can a 24-inch bag be a carry-on?

Yes, a 24-inch bag can be used as a carry-on suitcase when flying with the following airlines: Frontier, Southwest and Sun Country . However, if you're shopping for new carry-on luggage , it's best to opt for something that meets the requirements for most major airlines (22 x 14 x 9 inches or smaller).

Is there a weight limit for carry-on bags?

Most major domestic airlines do not impose a weight limit on carry-on bags; however, several international airlines have weight restrictions for carry-on luggage and, in some cases, personal items.

Carry-on vs. personal item: What's the difference?

A carry-on bag is typically stored in a plane's overhead bin, while a personal item should fit under the seat in front of you. Most airlines allow economy passengers to bring one carry-on and one personal item – such as an underseat bag – at no extra cost.

See all Alaska Airlines carry-on policies.

The fee is often around $20 if you pay for your carry-on baggage at the time of booking; it costs a hefty $45 if you add a carry-on bag later – and up to $75 at the gate.

See all Allegiant Air carry-on policies.

The above rules also apply to basic economy tickets.

See all American Airlines carry-on policies.

Note that if you're flying to or from Beijing or Shanghai, there is a 22-pound weight limit for a carry-on; for Singapore, there is a 15-pound limit.

See all Delta Airlines carry-on policies.

There are two instances where the carry-on bag fee is waived:

• You're an elite member of the  FRONTIER Miles rewards program .
• You bought a specialty ticket like the WORKS bundle.

Also note that carry-on bag fees, which typically start at around $30, depend on your destination, and that prices are cheapest if you add baggage when you make your booking. You'll pay more to add it later, especially if you do so at the airport. Sometimes it's actually cheaper to purchase a checked bag instead of a carry-on.

See all Frontier Airlines carry-on policies.

See all Hawaiian Airlines carry-on policies.

If you booked a Blue Basic ticket, you're only permitted to bring a personal item that fits under the seat in front of you. If you bring a carry-on bag, you will have to pay $65 to check it at the gate (or up to $180 if you've already checked two other bags). However, select customers with Blue Basic fares can bring carry-on bags for free. These include:

• Active U.S. military personnel
• Unaccompanied minors
• Customers flying to London

If you purchase a higher-class seat or if you reach Mosaic status on JetBlue's TrueBlue rewards program , you can also bring a carry-on bag for free on a Blue Basic ticket.

See all JetBlue carry-on policies.

See all Southwest Airlines carry-on policies.

Spirit's carry-on bag fees vary between flights, but they tend to start at around $25 to $30 for U.S. domestic flights. If you need to bring carry-on luggage, it's always cheapest to pay for it when you first book your flight. It will cost you more to add a bag afterward – and at least double the initial fee if you do it at the airport.

See all Spirit Airlines carry-on policies.

The Sun Country Airlines fee for a carry-on bag is around $30 if you pay for it when booking, or more if you add it later.

See all Sun Country carry-on policies.

There's one notable exception for carry-on baggage with United: Passengers with a basic economy ticket can only   take one personal item on board – no carry-on bag. This policy applies to travelers flying basic economy domestically or between the U.S. and Canada. If you have a basic economy ticket and are going to Central or South America (including Mexico) or taking trans-Atlantic or trans-Pacific flights, you can bring a full-size carry-on bag.

See all United Airlines carry-on policies.

Aer Lingus' carry-on policy depends on where you're flying. For trans-Atlantic flights, you can bring one carry-on bag within the dimensions above, plus a small personal item for free. If you're flying within Europe on Aer Lingus, the rules are a bit different: You'll have to pay a fee to bring a carry-on with you on board, starting at 5.99 euros. However, you can check that same bag for free.

If you're flying Aer Lingus Regional (a service with smaller planes, flying mostly around Ireland and the U.K.), a smaller carry-on limit applies: 18.5 x 13 x 8 inches, with a weight limit of 15 pounds.

See all Aer Lingus carry-on policies.

All Aeroméxico customers can bring a standard carry-on bag and a personal item on board. Be careful with the weight limit, though: For international flights or basic fare flights within Mexico, these two items combined cannot weigh more than 22 pounds. So, if your carry-on bag weighs 15 pounds, for example, your personal item cannot be more than 7 pounds.

See all Aeroméxico carry-on policies.

While there's no weight limit for carry-on luggage, Air Canada says your carry-on bag should be light enough that it can easily be lifted into the overhead bin. Also note that airport purchases (for example, larger duty-free items) count toward your baggage limit.

See all Air Canada carry-on policies.

Note that both your personal item and carry-on bag (referred to as "hand baggage") combined must not weigh more than 26 pounds if you're traveling economy. The weight limit is 40 pounds for premium economy and other higher-class cabins.

See all Air France carry-on policies.

A variety of personal items (think a handbag and umbrella) are permitted as long as they fit under the seat in front of you; this includes any items purchased at the airport.

See all All Nippon Airways carry-on policies.

If airline staff put a yellow tag on your bag, it should be stored under the seat in front of you.

See all British Airways carry-on policies.

Cathay Pacific has shifted from a weight allowance to a piece allowance, and this policy varies by itinerary. Passengers are generally permitted to bring one carry-on bag plus a small personal item (and assistive devices like a walking stick), but it's best to check your booking carefully to confirm the exact allowance. You're asked to check in any baggage that's too heavy to lift into the overhead compartment.

See all Cathay Pacific carry-on policies.

Since easyJet is a budget airline, standard fares only allow customers to bring one personal item (called a "small cabin bag") aboard for free. Fees for standard carry-on bags are between 5.99 and 32.99 British pounds, depending on your destination and when you add an extra bag to your reservation.

See all easyJet carry-on policies.

The above rules apply to all economy passengers except those traveling from Brazil, whose carry-on luggage can weigh up to 22 pounds. Emirates only allows economy passengers to bring one item on board; whether you bring a carry-on bag for the overhead bin or a personal item to tuck under the seat, this bag must comply with the size limits.

See all Emirates carry-on policies.

Be aware that the 22-pound weight limit applies to both your personal item and carry-on combined. If your flight was booked through Iberia but is operated by Vueling, similar rules apply, but the size limits for your carry-on bags are slightly smaller.

See all Iberia carry-on policies.

If you're traveling on the cheaper Light ticket, you may be asked to check your carry-on bag for no extra cost, if space is limited.

See all KLM Royal Dutch Airlines carry-on policies.

See all Lufthansa carry-on policies.

The above rules apply to LowFare+ customers. Passengers who fly LowFare (comparable to Basic Economy fare) can only bring a personal item (underseat bag) measuring 15 x 11.5 x 7.5 inches.

See all Norwegian carry-on policies.

Qantas 

Economy passengers can opt to bring a nonrigid garment bag measuring 45 x 24 x 4 inches (or 73 linear inches) instead of a standard 22 x 14 x 9-inch carry-on bag. The above rules apply to all economy tickets and vary for higher classes on international and domestic flights with Qantas.

See all Qantas carry-on luggage policies.

Qatar Airways allows passengers to bring multiple personal items provided they fit under the seat in front of you. Unlike with other airlines, laptops and laptop bags do not count as personal items and must fit within your main hand baggage allowance. For tickets issued in Brazil, the carry-on weight limit is 22 pounds.

Be careful: Qatar doesn't accept carry-ons longer than 20 inches, which is shorter than many other airlines.

See all Qatar Airways carry-on policies.

Ryanair is a low-cost carrier, so unless you pay extra, you can only bring one small bag that fits under the seat in front of you, per the personal item guidelines above. To bring a larger carry-on bag, travelers need to purchase Ryanair's Priority & 2 Cabin Bags option, which typically costs between 6 and 32 euros depending on your destination.

See all Ryanair carry-on policies.

Most (but not all) Scandinavian Airlines fares allow you to bring one traditional carry-on bag, plus a personal item, which SAS calls an "underseat bag." There's one exception: Passengers traveling within Europe on the Go Light fare must pay for a larger carry-on bag. If you booked a Go Light ticket for intercontinental flights, a carry-on bag is included.

See all Scandinavian Airlines carry-on policies.

Singapore Airlines has an unusual method for measuring carry-on bags – the dimensions of the bag must not add up to more than 45 linear inches total. For example, a bag measuring 15 x 15 x 15 inches would be suitable. All passengers can bring one bag of this size, plus a smaller personal item. The personal item, whose dimensions are specified above, does not count toward the 15-pound carry-on limit.

See all Turkish Airlines carry-on policies.

Virgin Atlantic lets every passenger bring a carry-on bag, including children younger than age 2.

Each passenger is also allowed to bring a handbag or small backpack, an umbrella, a walking stick and airport purchases. Take note: Laptops do not count as personal items on Virgin Atlantic and should fit into your main carry-on bag. There's no specific size limit on the other personal items, but bags or airport purchases should fit under the seat in front of you.

Amanda Norcross is a seasoned traveler who packs just one carry-on bag and a personal item – even when adventuring with her toddler . She used her personal experience and research skills to put together this guide, and notes that even if your carry-on bag meets size restrictions, you may still need to check it at the gate because of limited space in the overhead bin.
