Where can I use my American Airlines mobile boarding pass?
You can use your American Airlines mobile boarding pass at most airports. Before you leave, check to see if your departure or connecting airports accept mobile boarding passes. Visit the American Airlines official website and find your airport, then look under 'Airport details' to see if mobile boarding passes are available. If you still need to, you can print a boarding pass before you head to the airport or from any self-service kiosk once you're there.
