American Airlines carry-on: what fits and what doesn’t.
The maximum carry-on size for American Airlines is 22 x 14 x 9 inches, including wheels and handles. Your bag must fit in the overhead bin. If it doesn’t, you’ll need to check it at the gate – and you may incur a fee.
Last updated and fact-checked: May 19, 2026.
American Airlines doesn’t enforce a weight limit for carry-on bags. Just make sure you can lift it into the overhead bin yourself.
Your personal item can be up to 18 x 14 x 8 inches. It must fit comfortably under the seat in front of you. Think purses, small backpacks, laptop bags or briefcases.
If you’re in an exit or bulkhead row, all items must go in the overhead bin during takeoff and landing – nothing can stay at your feet.
American Airlines carry-on basics.
- Size is what matters most. Your carry-on is measured including wheels and handles, and you may be asked to place it in a sizing device at the airport. If it doesn’t fit, you’ll likely need to check it and pay a fee.
- The good news? There’s no weight limit for carry-on bags on American Airlines fares – as long as your bag meets size requirements and you can lift it into the overhead bin.
- TSA’s 3-1-1 rule means liquids in your carry-on must be in containers of 3.4 oz (100 ml) or less, all packed in one clear quart-sized bag, with exceptions for essentials like medications, baby formula and breast milk.
- All fares, including Basic Economy, include 1 carry-on bag and 1 personal item for free. Your carry-on goes in the overhead bin, while your personal item should fit under the seat in front of you.
- The tradeoff? Checked bags usually aren’t included. If you need to check luggage, you’ll typically pay a fee, though some international routes may include one. It’s worth checking your specific fare details, as allowances can vary by route.
What doesn’t count as a carry-on?
Good to know: the following don’t count toward your allowance for a personal item or carry-on, so you can bring them on board stress-free.
- Child safety seats
- Strollers
- Medical or mobility devices such as canes
- Diaper bags (one allowed per child)
- Breast pump
- Small, soft-sided cooler of breast milk
What extra items can you bring on board?
- Musical instruments can fly as carry-ons if they fit in the overhead bin or under the seat.
- Pets are welcome too. Their carrier just needs to fit under the seat.
- No weight limit for instruments or pet carriers, as long as they fit.
- Sports gear or other oversized items may have special rules (worth checking American Airlines' policy before you go).
- Strollers can be gate checked. Just ask for a tag so it's waiting at your arrival gate.
If you want to gate check an item like a stroller so you can use it in transit, be sure to see the gate agent for the appropriate tag. This way, it won't be sent to baggage claim instead of being unloaded at your arrival gate. Blane Bachelor, travel expert
Tips for flying with a carry-on on American.
from expert traveler Blane Bachelor
1. Carry-on in exit rows.
If you’re sitting in an exit or bulkhead row, you’ll need to put all your carry-on items in the overhead bin for takeoff and landing. So don’t wait to board until the last group, when that critical space will likely be full.
2. Board with your group.
Overly eager travelers on American Airlines, beware: The carrier recently introduced technology to identify so-called “gate lice”: passengers who try to board ahead of their group (and presumably grab bin space for their carry-ons).
Board with your group, or you may be sent to the back of the line.
3. Personal item goes under the seat.
Don’t assume you can store a personal item – say, a backpack – alongside your larger carry-on in the overhead bin, especially if you have a basic economy fare.
One, bins may be full by the time you board; and two, the carrier may slap you with a gate service fee for personal items deemed too big.
