Turkish Airlines offers a flexible cancellation policy, so you can do so if you have tickets with the airline but need to cancel for urgent or personal reasons. Customers will profit considerably from taking full advantage of Turkish Airlines Change Flight, which allows reservations to be cancelled free of charge within 24 hours of the initial purchase on the same day. If a customer cancels their reservation, they will be entitled to a full refund, but only if they do so at least seven days before the flight's planned departure. All refundable and non-refundable tickets are eligible for a full refund if cancelled within 24 hours of departure.
