For all tickets
24-hour refund: You can receive a full refund to your original form of payment if you cancel within 24 hours of booking, as long as your flight is booked at least two days before departure.
No cancellation fee: For most ticket types (non-refundable Main Cabin, Premium Economy, and higher), American Airlines has eliminated cancellation fees. Call at +1-888-415-1245 (US) or +44-203-869-5245 (UK) Instead of a refund, you will receive travel credit for the value of your original ticket.
Cancellation must occur before departure: You must cancel your ticket before the first flight departs. Otherwise, the ticket loses all value and cannot be used for future credit.
