How do I add a seat on American Airlines?

When you book a flight operated by American, you'll see the seat map after you choose your flights. Go to “My trips/check-in” from the homepage and enter your name and record. From there, you can choose seats. If seats are unavailable, check back later or you can change seats when you check in.



To add or change a seat on American Airlines in 2026 after you have already booked your flight, you should log in to the "Manage Trips" section on AA.com or the American Airlines mobile app. Once you enter your record locator (the 6-character code), you can view the live seat map for your flight. From there, you can select any available seat; while "Main Cabin" seats may be free depending on your fare, "Preferred" or "Main Cabin Extra" seats will require an additional fee (typically $15 to $120). If you are flying on a Basic Economy fare, you may be charged a fee to select any seat before check-in; otherwise, one will be assigned to you for free at the gate. If you have any trouble online, you can call American's customer service or use the "Chat" feature in the app, which is often faster during peak travel times.
