To cancel your American Airlines ticket and*************, the key factor is understanding your ticket type. If you have purchased a refundable ticket, canceling your flight will result in a full refund. If you’ve purchased a non-refundable ticket, you may not receive a cash refund but could be eligible for a travel credit instead. American Airlines also offers a 24-hour cancellation window that applies to all tickets, giving you a chance to cancel for a full refund if done within 24 hours of booking, as long as the flight is at least two days away.
