American Airlines Carry-On Rules: Everything Need to Know!

If you're planning to travel with just a carry-on, you'll need to be up to speed with airline carry-on policies. Specifically, the various rules and regulations each carrier has for what you can and cannot “carry-on” to the plane. Each airline’s rules are different, so don’t just assume what works for one will work for all airlines.

Here are the American Airlines Carry-On rules that you need to be aware of:

American Airlines Carry-On Bag Guidelines

American Airlines allows one personal item and one carry-on bag at no charge.

What does American Airlines consider a Personal item?

Personal items include a purse, briefcase, laptop, backpack, shopping bag or a similar sized item. Dimensions should not exceed 18 x 14 x 8 inches (45 x 35 x 20 cm).

Diaper bags (1 per child), soft-sided cooler bags with breast milk, child safety seats, strollers and medical or mobility devices don’t count as your personal item or carry-on.

American Airlines Carry-On Bag Guidelines for Basic Economy Fares

There is no charge to carry a bag on when you buy an American Airlines Basic Economy fare. The carry-on rules are the same for all classes of service. However, with a Basic Economy ticket, you will be one of the last to board, so overhead space will be limited.

American Airlines Carry-On Dimensions

American Airlines’ size requirements for a carry-on are 22″ x 14″ x 9″.

If you are not sure what size your carry on is, American Airlines does provide size check templates located at their ticket counters and gates. But by the time you get to either of these locations it’s too late if the bag is too big, so better to always know your bag size in advance.

Soft-sided garment bags up to 51 inches / 130 cm (length + width + height) can also be taken as your carry-on item.

American Airlines Carry-On Weight Limits

As a rule, American Airlines does not impose weight restrictions with a carry-on bag.

American Airlines Carry-On Rules for Small Regional Aircraft

American Airlines regional aircraft have limited overhead space. If your carry-on is larger than the personal item dimensions, you must gate check your bag before boarding.

Carry-on bags within American Airlines’ size restrictions will be gate checked, free of charge, during the boarding process and returned upon deplaning. Depending on the time of year and where you are flying to, this will give you the opportunity to hang out with 50 of your newest friends in either a steaming hot or freezing cold jet bridge. Fun!

Despite this “official rule” there are some bags you can carry on to a regional jet. Check out this article on the best carry-on luggage for regional jets.

American Airlines Carry-On Prohibited Items

There certain items are considered dangerous and classified as hazardous material. Dangerous goods are prohibited from both your carry-on and checked bag in all American Airlines flights. These rules are not specific to American Airlines and are mandated by the Federal Aviation Administration.

The list includes items such as aerosols, fireworks, matches, etc… A complete list can be found on the FAA website and the TSA website.

American Airlines Carry-On Liquids

The rules for carry-on liquids are set by the TSA and FAA. American Airlines doesn’t make the rules, but they must enforce them.

The TSA 3-1-1 Rule

Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.

Any liquid that does not meet the TSA 3-1-1 rule will either have to be checked with your luggage or will be thrown away at the security check point.

Here is a little video to help illustrate:

Exceptions to this rule are certain medications and baby food / child nourishments.

American Airlines Carry-On Food

There are two different scenarios here. Food you bring with you from home and food you buy at the airport, after you have gone through security.

Any important thing to note is the classification of liquid vs. solid foods. The general rule is “If you can spill it, spread it, spray it, pump it, or pour it, then it’s considered a liquid or gel,”. This means your food may be considered a liquid and will fall under the TSA 3-1-1 liquids rule, which mandates that any liquid, gel, cream, aerosol, or paste in a carry-on must be 3.4 ounces or less, and fit in one quart-size resealable bag (only one such bag is allowed per passenger).

Here is a link to the TSA website advising what food can be brought with you on your American Airlines flight. This applies to food you are bringing from home through security. Once you get through security, you can bring just about any food on the plane that you buy at the airport.

American Airlines Carry-On Pet Policy

On American flights you can bring 1 kennel as your carry-on bag if:

You pay the carry-on pet charge
Your pet stays in the kennel and under the seat in front of you the entire flight

You can travel with your pet carrier and one personal item, but you won’t be permitted to bring a carry-on bag in addition to a pet carrier and personal item. Instead, the kennel will replace your carry-on bag.

Carry-On Pet Fees

Here is a chart showing the pet fees American Airlines charges each way. Double them for a round trip flight.

To/From Destination	Pet Fee Each Way
Within and between the United States and Canada, Mexico, Central America, Colombia and the Caribbean (based on specific country's entry policy)	$ 125.00

Service animals has some separate guidelines. Here is a link to AA’s service animal rules.

TSA Approved Pet Carriers

If you do plan on bringing your pet with you, make sure you follow TSA's pet policy and have an approved Pet Carrier that conforms to American Airlines’ pet policy.

American Airlines Carry-On Fee

American Airlines does not charge a fee for carry-on baggage that meets their size requirements. If your bag is too large and does not meet American Airlines’ carry on restrictions, you may be charged a fee to gate check it.
