To obtain a refund from American Airlines, the process primarily depends on whether your ticket is "Refundable" or "Non-Refundable." For Refundable tickets, you can request a full refund to your original payment method via the "Manage Bookings" section on aa.com or the mobile app. For Non-Refundable tickets, a cash refund is generally only possible if you cancel within 24 hours of booking (provided the flight was booked at least 2 days before departure). In most other cases, you will receive a "Flight Credit" rather than a refund. However, if American Airlines cancels your flight or makes a significant schedule change (typically defined as more than 4 hours), you are legally entitled to a full cash refund regardless of ticket type. You can file these formal requests through the dedicated https://www.google.com/search?q=prefunds.aa.com portal. Always ensure your AAdvantage number is linked to the reservation before canceling to streamline the automated processing of your claim.
