Your most recent Turkish Airlines Cancellation Policy will be cancelled? You may choose to do this whenever your flight reservation is confirmed. This might happen to anyone whose flight needs to be delayed for any reason, including an emergency of any kind. Turkish Airlines has a cancellation policy that permits passengers to change their flight schedules and get a refund. The amount of the reimbursement will also depend on the flight type you booked.
