Contact American Airlines Immediately
As soon as you realize youā€™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 youā€™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.
