How Early Can I Check In for my American Airlines Flight?

When getting ready for your upcoming trip on American Airlines, you can start the check-in process from 24 hours to 30 minutes prior to your scheduled departure time through the airline’s website or mobile app. Simply access your reservation at American Airlines Check-In online, choose your seat, obtain your boarding pass, and, if needed, print bag tags well before arriving at the airport. You can visit the American Airlines website or call their customer support center at 800-433-7300 or +1-844-902-4930 (OTA: Skip Waiting).
