Yes, American Airlines does provide full refunds under certain circumstances. In general, if American Airlines cancels a flight or makes changes to the schedule that doesn't suit your travel plans, you are entitled to a full refund. However, if it is the passenger who decides to cancel their ticket voluntarily, the refund policy may vary depending on the fare type and ticket conditions. For instance, if you have purchased a non-refundable ticket, you may not be eligible for a full refund but could receive a credit towards a future booking instead. more info contact Airlines.
