Whether you’re flying domestically or internationally, every airline has its carry-on luggage size restrictions. There is no one-size-fits-all approach, so you need to check your airline’s specific policy before traveling to ensure your carry-on bag isn’t rejected with potential additional charges.

Below, you’ll find a helpful chart detailing the most popular airlines’ carry-on restrictions, including the size and weight of a standard carry-on, and whether this varies due to the cabin you’re traveling in. We’ve also covered checked luggage sizes and allowances, too.

Don’t forget that there are many ways to avoid paying for baggage fees such as carry-ons and that’s what we cover in our in-depth article.

In some cases, you’ll see that the airline has a rule about maximum linear dimensions. That means that when you add a piece of luggage’s length, width, and depth together, the sum can’t exceed a specific number.

For example, if you have a suitcase that’s 28 inches long, 20 inches wide, and 18 inches deep, the linear dimensions would total 66 inches, too big for many airlines.

Carry-On Luggage Size Chart for Major Airlines

Unless specified, the maximum weight allowance is across your standard carry-on luggage and personal item combined. 


Frequently Asked Questions

What is considered carry-on luggage?

There’s no industry standard for sizes for carry-on luggage, with every airline assigning their own size and weight restrictions. If you want to purchase a carry-on bag that would be accepted by most airlines, then the most common maximum size would be 22 x 14 x 9 inches (56 x 36 x 23 cm), including handles and wheels.

Which carry-on luggage is best?

The best carry-on bag depends on your own requirements. For example, do you need a wheelie case or a backpack, or a bag with a laptop compartment or built-in security? We’ve rounded up what we consider the best carry-on luggage bags for any traveler, ranging from soft-sided and hardshell wheelies to convenient backpacks.

Is a backpack considered carry-on?

A backpack would be considered a carry-on item if it adheres to the maximum size restrictions of a specific airline. Most airlines have a larger size allowance for a standard carry-on piece and slightly smaller one for a personal item (where permitted).

What is not allowed in a carry-on bag?

For safety reasons, there are certain items that are prohibited to be stored in carry-on luggage. These include individual containers with liquids over 3.4 ounces (100 ml) or a combined amount of liquids over 1 quart (1 liter); sharp objects such as scissors, blades, or pen knives; firearms; sporting equipment such as baseball bats or hockey sticks; tools; and lighters, matches, or other flammable items.

Is there a weight limit for carry-on luggage?

As with size restrictions, there are no industry standards for maximum weight allowances for carry-on luggage. These are defined by each individual airline, with some airlines actually not publishing a specific weight restriction — just that you must be able to lift the bag into the overhead compartment yourself.

It’s also worth checking whether the airline’s stated weight allowance applies just to your carry-on piece or whether it applies to the combined weight of your carry-on and personal item.

What is the difference between a personal item and carry-on?

Many airlines allow passengers to bring a personal item in addition to a carry-on bag. A personal item is usually a smaller bag, such as handbag, briefcase, or laptop bag, that can be stored under the seat in front of you. Some airlines specify size and weight restrictions for personal items, while many don’t specify maximum sizes or weights.

What is hand baggage only?

If you’ve booked a “hand baggage only” fare (sometimes referred to as a basic fare), this means that you may only bring hand baggage that is within the airline’s restrictions. No checked baggage is included. Depending on your airline, hand baggage may include 1 standard carry-on bag and 1 smaller personal item. Each airline sets its own size and weight restrictions for carry-on, so check the table above for more information.

What does TSA allow for carry-on?

TSA allows passengers to pack certain items in their carry-on baggage and prohibits others. Liquids may be brought on board under the 3-1-1 rule: a maximum of 3.4 ounces per container up to a total of 1 quart, stored within a clear, zip-top bag, with 1 bag permitted per passenger. Exemptions to this rule are made for infant necessities or required medication. Items such as lighters, blades, and baseball bats are not permitted in your carry-on.

See more information in our guide to how to easily get through TSA airport security.

What is the standard size of a carry-on bag?

There are no universal standards for carry-on baggage, with each airline setting its own size and weight restrictions. If you want to purchase a bag that adheres to most airline standards, then look for a case that’s no larger than 22 x 14 x 9 inches (56 x 36 x 23 cm), including all handles and wheels.

Can I take my phone charger in my carry-on?

General chargers for electronic devices can be packed as carry-on or into your checked baggage. If you’re using a portable power bank, then most airlines require you to pack this in your carry-on bag. This is because of the risk of lithium batteries catching fire in the hold.

Is a 24-inch suitcase a carry-on?

A 24-inch suitcase would be considered a carry-on by some airlines — but not all. Some airlines state maximum linear dimension only, so as long as your other 2 measurements are smaller to allow for the 24-inch length, then this would be fine. But generally, a suitcase measuring 22 x 14 x 9 inches would be the most widely accepted. This includes American Airlines and United Airlines.
