American Airlines Check In +1 - 866 - 551 - 1186

Planning to fly with American Airlines? You can check in online or through the app up to 48 hours before your flight—unless you're flying to or from the U.S., in which case check-in opens 24 hours ahead. Prefer the airport? Counters and kiosks are there to help! You'll be able to pick a seat, add any bags, and get your boarding pass. Don’t forget to arrive at the airport at least 3 hours early to keep things stress-free.
