How American Airlines check-in generally works
The timing and steps, in plain English.
Online check-in on aa.com and the American app generally opens 24 hours before departure and closes shortly before the flight.
Bag-drop and boarding cutoffs vary by airport and by domestic vs. international — arrive early for international departures.
Boarding is by groups shown on your boarding pass; premium cabins, elite status and certain cards board earlier.
Checking in early usually improves your seat availability and standby position.
International trips need valid travel documents; requirements vary by nationality and destination.
Cutoffs and rules vary by airport, route and fare. If anything goes wrong at check-in, call us and we'll work it out with you.
