Qatar Airways' cancellation policy varies depending on the fare type and destination. In general, if a booking is canceled before the scheduled departure, a fee will be charged and any remaining funds will be issued as a credit for future travel. If a flight is cancelled by Qatar Airways, customers will have the option to receive a refund or be rebooked on an alternate flight. It is recommended to check the specific terms and conditions of your booking or contact Qatar Airways directly for more information on their cancellation policy.
