American Airlines cabin bag size
Everything you can bring on board American Airlines — sizes, weight and cost.
American Airlines cabin baggage explained
American Airlines includes one carry-on and one personal item, including on Basic Economy. It publishes fixed maximum dimensions for both, which makes the result easier to calculate than a policy based only on “fit under the seat.”
What your fare changes
The personal item is limited to about 18 × 14 × 8 in (45 × 35 × 20 cm). The carry-on is about 22 × 14 × 9 in (56 × 36 × 23 cm). Both are included, while checked-bag pricing is a separate part of the ticket.
What to check before you fly
The carry-on measurement includes wheels and handles and the bag must fit the airport sizer. Smaller regional aircraft or airports can impose additional restrictions, so keep essentials in the personal item if the larger bag is valet-checked.

Cabin bag / carry-on ≈ 22 × 14 × 9 in, including wheels & handles. | 56 × 36 × 23 cm 22 × 14.2 × 9.1 in | — | All fares | Free |
Worked bag-size example
Take a US-size roll-aboard measuring 55 × 35 × 22 cm. Compare it with the cabin-bag limit of 56 × 36 × 23 cm.
The smallest dimensional margin is 1 cm, so the bag is within the size limit.
We compare the three outside edges after orientation, including protruding parts. A result with less than 0.5 cm of clearance is marked tight because measuring and packing can change the real size.
