Quick answer
Yes, a standard backpack, tote, or laptop bag fits as a personal item on American Airlines as long as it measures under 18 x 14 x 8" (45 x 35 x 20 cm) and fits fully under the seat in front of you.

Frequently asked questions
What is the American Airlines personal item size limit?
American Airlines allows a personal item up to 18 x 14 x 8" (45 x 35 x 20 cm). Must fit under the seat. Diaper bags and medical devices do not count.
Does a backpack count as a personal item on American Airlines?
Yes. A standard daypack or laptop backpack (about 18 x 13 x 8 inches) fits within the American Airlines personal item limit of 18 x 14 x 8". Larger travel or hiking backpacks may exceed that limit and will be treated as a carry-on.
Does American Airlines weigh personal items?
Personal item weight is not published by American Airlines and is rarely enforced at the gate for US domestic flights. On international routes, especially with codeshare partners, agents may weigh bags, so keep your personal item reasonable in weight.
What if my personal item is too big for American Airlines?
If your bag exceeds 18 x 14 x 8", a gate agent can ask you to place it in the sizer. If it does not fit, you may need to pay a carry-on or checked bag fee. On Basic Economy fares, an oversized personal item is the most common cause of surprise fees.
Can I bring a personal item plus a carry-on on American Airlines Basic Economy?
Often no. American Airlines restricts Basic Economy passengers to a personal item only on many routes, with full-size carry-ons either banned or charged as a paid add-on. Read the fare rules at booking before you pack.
