American charges $5 more per checked bag on Basic Economy, and $5 more again if you pay at the airport. Those two small penalties are the quiet cost inside American Airlines baggage rules today.
The allowances themselves are standard. A 22 x 14 x 9 inch carry-on, an 18 x 14 x 8 inch personal item, and 50 pound checked bags at 62 linear inches.
American Airlines baggage rules reward paying early
The first checked bag is $50 at the airport but $45 if you pay online beforehand. The second is $60, or $55 online.
A couple checking one bag each on a round trip pays $20 more at the counter. For nothing.
Set a reminder when you check in. It is the easiest saving available on any US carrier.
American Airlines baggage rules keep your carry-on on Basic Economy
American, like Delta, still allows a full size carry-on on Basic Economy. You keep the personal item too.
What Basic Economy costs you is $5 extra per checked bag. With the airport surcharge on top, a walk up Basic Economy bag reaches $55.
That differs sharply from United, which removes the carry-on from Basic Economy.
The personal item is bigger than you think
American publishes an 18 x 14 x 8 inch personal item. That is noticeably larger than United’s 17 x 10 x 9.
Four extra inches of width matters. A backpack that counts as a personal item on American may not on United.
If you fly Basic Economy on both carriers, pack to the smaller of the two. It is the only way one bag works on both.
Where American Airlines baggage rules get fiddly
Most carriers publish one or two overweight bands. American publishes several, and they vary by destination.
That detail cuts both ways, as the table shows.
| Weight or size | Fee |
|---|---|
| 51 to 53 lb | $30 |
| 53 to 70 lb | $100 to $200 by destination |
| 70 to 100 lb | $200 to $450 by destination |
| 62 to 65 linear in | $30 |
| 65 to 115 linear in | $150 to $200 by destination |
The 51 to 53 pound band is worth knowing. A bag barely over the line costs $30, not the $100 most airlines charge.
Nothing above 100 pounds or 115 linear inches is accepted at any price.
Who avoids the fees
Checked bag fees are waived for AAdvantage Gold and above. Eligible American credit cardholders skip them too, as do premium cabin and military fares.
Fly American more than twice a year and the airline credit card usually covers its own fee in bag savings. That is arithmetic, not a recommendation.
The bottom line
The allowances match the industry standard almost exactly. It is the pricing that has edges.
American differs in the small surcharges. It adds $5 for Basic Economy and $5 for paying late, then softens the first overweight band.
Compare it against the other carriers and check the checked baggage rules. The size checker confirms your bag before you leave.
