If you are taking a flight on American Airlines, you have the option to pay for any checked bags at the time of online check-in on aa.com. Check-in begins 24 hours before your flight and continues up to 4 hours before your flight for purposes of paying for checked bags.
Other notes to know:
- You can only pay for checked bags online for U.S. domestic flights, not international flights. Hawaii and Alaska are considered U.S. domestic flights.
- You can pay for up to 3 bags when you check in on aa.com or on the American Airlines app.
- You’ll get an email confirmation that will have instructions on where to drop bags at the airport.
- You can not pay for baggage fees over the phone, only online or through the AA mobile app.
For other information on baggage fees, including potential refunds for cancelled flights, see this page on the AA site.
