Reading through terms and conditions to comprehend airline regulations can be challenging. The key elements of American Airlines' flight cancellation policy are summarised as follows:

When purchased at least two days before departure, all tickets can be cancelled for a full refund within 24 hours of the purchase.

Tickets that are cancellable for a full refund can be done so online or by getting in touch with reservations.

Tickets that are nonrefundable: no refunds after the 24-hour grace period. However, if a flight is cancelled prior to takeoff, you may utilise the unused portion of eligible tickets against another trip, provided the new flight occurs within a year of the original ticket issue date.
