American Airlines baggage costs depend on your route, fare type and elite status. This guide covers the carry-on allowance, checked-bag prices and the size and weight limits, and shows where travelers most often get caught by extra fees.
Carry-on allowance
On most American fares you can bring one carry-on bag plus one personal item (a purse, laptop bag or small backpack) at no charge. The main exception is Basic Economy on some routes, where a full-size carry-on may not be included — check your fare before you pack.
The carry-on must fit in the overhead bin; the personal item goes under the seat. If the flight is full, gate agents may check carry-ons for free, but you keep valuables and essentials with you.
Checked bag fees
For domestic economy, the first and second checked bags each carry a fee that you'll see during booking or check-in; prices are lowest when you pre-pay online rather than at the airport. Fees rise for a third bag and for overweight or oversized items.
Many long-haul international fares, premium cabins and elite/co-branded card holders include one or more free checked bags. If you're close to a status tier or hold an American-branded card, confirm your allowance before paying.
Size and weight limits
Standard checked bags must not exceed 50 lb (23 kg) and 62 linear inches (length + width + height). Bags over these limits trigger overweight or oversized fees that can cost more than the ticket's bag fee itself.
Weigh your bag at home. Redistributing a few pounds into a carry-on, or splitting into two bags, is often cheaper than a single overweight charge.
How to avoid extra charges
Pre-pay bags online, travel with a fare or card that includes an allowance, and stay under the 50 lb limit. If you're planning a whole trip, a travel advisor can factor bag fees into the true cost comparison between fares and airlines.
Booking a flight-plus-hotel package or premium cabin sometimes includes baggage that makes a slightly higher fare cheaper overall — worth comparing before you book.
