If you already have tickets with Turkish Airlines but need to cancel for urgent or private reasons, you may do so because of the airline's accommodating cancellation policy. The Turkish Airlines Flight Change Policy, which permits bookings to be cancelled within 24 hours after the initial purchase on the same day without incurring any cancellation fees, should be fully utilised by customers. A full refund is available to customers who cancel their reservations, but only if they do so at least seven days before the flight's planned departure. If cancelled within 24 hours before departure, all refundable and non-refundable tickets are eligible for a full refund.
