Before you board your next flight, make sure you are aware of your airline’s carry-on policies. Each airline has a separate set of rules, so don’t just assume that what works for one will work for all airlines.
In this article, we’ll explain everything you need to know about American Airlines’ carry-on policy including carry-on size and weight limits, liquid policy, personal items, and other rules and restrictions you should know before boarding your flight.
American Airlines Carry-On Policy
American Airlines allows one personal item and one carry-on bag at no charge. The personal item must be small enough to be stored under the seat in front of you.
Carry-On Bag Size & Weight Restrictions
American Airlines requires your carry-on bag to be no more than 22″ x 14″ x 9″ (56 cm x 36cm x 23cm). Your personal item cannot exceed 18″ x 14″ x 8″ (45 cm x 35cm x 20cm) Both measurements include the handles and wheel of your carry on.
Soft-sided garment bags that measure up to 51 inches / 130 cm (length + width + height) can also be taken as your carry-on item.
Musical instruments are also considered a carry-on item and must fit in the overhead bin or under the seat in front of you.
As a general rule, American Airlines does not impose weight restrictions on carry-on bags or personal items.
American Airlines Bag Sizer
If you aren’t sure what size your carry-on is, American provides “Bag Sizers” located at both the ticketing counters and the departure gates. If your bag will fit into the sizer, then you are all set to bring it on board with you. If it does not fit, you will have to check the bag.
Recommended Carry-On Bag When Flying AA
When flying American, I recommend the Travelpro Maxlite 5 Expandable Spinner. I have used this carry-on for years. It’s durable, reasonably priced, and holds everything I need for 3-4 day trips.
This carry-on bag has been sizer bin tested to accommodate overhead bin space on most major US airlines.
Case Dimensions:
- H: 21 in. W: 14 in. D: 9 in.
Note: If fully expanded it may not meet overhead bin size limits, so be careful to not overpack.
American Airlines Personal Item Size
Personal items include a purse, briefcase, laptop, backpack, blanket, shopping bag, or a similar-sized item. Dimensions for a personal item 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, breast pumps, child safety seats, strollers, and medical or mobility devices don’t count as your personal item or carry-on.
American Airlines Carry-On Liquids
The rules for carry-on liquids are set by the TSA (Transportation Security Administration), not by the airline. American Airlines doesn’t have its own specific Liquids Policy, they just enforce the rules and policies of the TSA.
It’s also important to note that the rules for bringing a “liquid” in your carry-on bag are different from the rules that govern what you can bring in your checked luggage. Liquids in a carry-on bag must be 3.4 ounces or smaller and fit in a 1 quart-sized container. Anything larger must be placed in your checked luggage.
- All liquids, gels, pastes, and aerosols must be in a container of 3.4 ounces or smaller.
- All liquids must be in a resealable quart-sized clear plastic bag that is removed from your carry-on during the TSA screening process.
- Special exceptions are in place for items such as medication, formula, breast milk, etc.
- Food and Drinks purchased once you have cleared TSA checkpoints are not included in these restrictions.
TSA allows certain duty-free liquids through security in your carry-on bag if they’re packaged in a security tamper-evident bag. If you’re traveling with liquids or are unsure about any item, please contact the TSA.
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 fee
- 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 policies) | $ 125.00 |
Service animals have 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.
I have traveled with 2 dogs over the last 10 years, one was a 20 lb. Shih Tzu-Bichon (in the picture above) and another is a 12lb. Chihuahua mix. We used the Sherpa pet carrier when bringing them on a flight with us and it worked great!
Features mesh panels so your pet can breathe easily, a non-slip shoulder strap, locking zippers, and a rear storage pocket for treats and other goodies.
Approved for use on most major airlines and the small and medium sizes are included in Sherpa's exclusive Guaranteed on Board program.
Prohibited or Restricted Items
There are certain items that are considered dangerous and classified as hazardous materials. Dangerous goods are prohibited from both your carry-on and checked bag on all flights. These rules are not specific to any airline and are mandated by the Federal Aviation Administration.
A list of prohibited or restricted goods and materials can be found in the following resources:
Summary: American Airlines Carry-On Policy
In conclusion, make sure you review American Airlines’ carry-on rules before packing for a trip and heading to the airport. They have size restrictions for carry-on bags, so it’s important to check the dimensions and weight of your luggage before arriving at the airport. Or you might end up paying unwanted fees.

Frequently Asked Questions:

I have to bring my diabetes kit with me. Can I keep that in my carry on or my personal bag. It contains a monitor, lancets and measuring tabs.
Hi Roseann – you can bring it on the plane with you in either your carry on bag or personal item. The general rule is to always bring your medications on board with you since there is a chance a checked bag can be lost or delayed.
I have a sholder bag which matches my carry on bag. It is 18.5 x 8×10 will that be allowed as a personel item?
Hi Margaret – If it will fit under the seat in front of you, it should be fine. Based on the size you stated I think it should not be an issue.
Does American require meds to be in their original bottle, or can meds be put in pill packs?
Pill packs should work just fine. Unless it is a powder or liquid.
I read your article. Didn’t see anything about a fold over garment bag for a suit. Is this item allowed as a carry on? Thanks.
Hi Jo – Yes. A garment bag is allowed as your carry on. But you cannot have a garment bag AND a carry on bag, you can only have a garment bag and one personal item. Anything else will have to be checked.
Does a garment bag have to be 22″ x 14″ x 9″ can it be 23″L x 8″W x 22.5″H?
Hi Dean – that is larger than what is stated as the maximum size. However, the nice thing about garment bags is they are collapsible so as long as you can fit it in the overhead bin you should be fine. Just be aware that if it does not fit, you may have to check it.
Apparently American count people when they are loading and have a carry-on cut off after so many people. I was in line and told to check my bag or find another flight. I have three connecting flights so I had to and they took both mine and my husband‘s carry-in’s and when we got on the plane I realize they checked it to our destination, which is in more than 24 hours, next destination were in the bag. Our meds are in the bas as well a a Epi pen. They wouldn’t pull it back for us. The worst part is that there were open slots in the overhead and I asked the flight attendant and she basically ignored me. Not a good practice. Had I known in advance I would have prepared
I need to bring medication with me in my flight. What do I put it in so that I can have it with me ?
Hi Sheila – You can bring your medication in pill or solid form in unlimited amounts as long as it is screened when going through the TSA checkpoint. Just about any pill case will work. You can search amazon for TSA approved pill cases and find a lot of options.
Has anyone had a problem with this case? Samsonite Freeform Hardside, Carry-On. As it is slightly larger than they alow at 23”H x 15”L x 10”W. All reviews on Amazon say no problems. But should I risk it?
Hi David – If you are flying American, Delta, or United, you are probably fine, worst case you will have to gate-check it. If you are flying a discount airline, all bets are off…
You have conflicting information for the size of a personal carry-on.
At the top of the article it states 18x14x8 and the image of the American Airlines sizing device at the airport shows the same.
Then at the end of the article under “can I bring a backpack as a personal carry-on” you say as long as it does not exceed 8x14x8.
So which size is the maximum amount for AA airlines?
Thanks Scott – 18x14x8 is correct. I was missing a digit in the backpack question. It has been updated. Good catch!
It would also be helpful to add whether or not there is a weight restriction to the carry-on bag. Some airlines do make it known how much is excessive for a carry-on, but American Airlines does not mention a weight restriction for carry-on bags. I was hoping you would know.
Hi Lydia – The major domestic airlines (American, United, and Delta) are strict about the weight of your checked baggage but I have never seen a situation where they have weighed a carry-on bag. As long as the weight is not blatantly excessive, you won’t have anything to worry about regarding your carry-on baggage weight. Just make sure it will fit in the overhead bin and you should be all set!
My first time flying. I have a few mediations I need with me. Will AA allow me to bring in carry on bag ? A what should I put the pills in ?
