Full Analysis
American includes a full-size carry-on on every fare type, including Basic Economy. United Basic Economy on most domestic routes includes a personal item only. If you book the cheapest fare and carry a normal suitcase, that distinction is worth roughly $50 each way.
American cabin baggage limits
| Bag type | Limit | Cost |
|---|---|---|
| Carry-on | 22 x 14 x 9 in (56 x 36 x 23 cm), including wheels and handles | Free on all fares |
| Personal item | 18 x 14 x 8 in | Free on all fares |
American checked bag fees (2026)
| Bag | Prepaid online | At the airport |
|---|---|---|
| 1st checked bag | $45 | $50 |
| 2nd checked bag | $55 | $60 |
| 3rd checked bag | $200 | $200 |
These rates apply to domestic and short-haul international travel on tickets booked on or after April 9, 2026. From May 18, 2026, Basic Economy passengers pay an additional $5 per bag on domestic itineraries. Fees are charged per direction, so a round trip with one checked bag costs $90 prepaid.
Size and weight limits
- Checked bag maximum: 62 linear inches (length + width + height).
- Standard weight limit: 50 lb per bag in economy.
- Premium cabins and AAdvantage elite status raise the allowance, commonly to 70 lb.
- Bags over 100 lb are not accepted.
Who checks bags free on American
- AAdvantage Platinum Pro and Executive Platinum: up to three free bags.
- Citi / AAdvantage Platinum Select and select co-branded cardholders: first bag free on domestic itineraries for the cardholder and companions on the same reservation.
- Active-duty military on orders.
- Premium cabin tickets include bags at the higher weight allowance.
What this means for the bag you buy
American uses the same 22 x 14 x 9 carry-on standard as Delta and United, and the same 62 linear inch checked limit as everyone else. That means one well-chosen bag works across all three, plus Southwest, which is more generous at 24 x 16 x 10. The expensive mistake is buying to a marketing size — "20 inch carry-on" — instead of to the measured exterior with wheels and handles attached.
The Problem
American is the only one of the big three that still gives Basic Economy passengers a full-size carry-on, and that difference is easy to miss when you are comparing fares on price alone. The second confusion is the two-tier fee: American charges one price online and a higher one at the airport, so the number you see on a fee table depends on when the writer looked.
Options
Free up to 22 x 14 x 9 in, on every fare including Basic Economy.
Free. Personal item capped at 18 x 14 x 8 in.
$45 prepaid online, $50 at the airport, each way.
$55 and $60, or $45 and $55 if prepaid.
Scenario Recommendations
- Prepay online or in the app. American keeps a $5 per bag discount for bags paid through its own channels, and the airport price is the higher one.
- If you are choosing between American and United Basic Economy, the free carry-on at American can be worth more than a small fare difference.
- Measure wheels and handles. American counts them, and a bag sold as "20 inch" can still exceed 22 inches overall once the handle housing is included.
