Contact American Airlines Immediately
As soon as you realize you’ve missed your flight, the first thing you should do is contact American Airlines. Call their customer service at 888-447-6026. The sooner you reach out, the sooner you can discuss your options for rebooking. If you’re still at the airport, go to an American Airlines customer service counter for assistance. Be prepared to provide your flight details, booking reference number, and any other relevant information.
