You can cancel your Turkish Airlines tickets up to one hour before takeoff for a fee. If passengers cancel their tickets more than 24 hours after making the initial purchase, they will be charged a fee. Cancellation fees vary by route, passenger class, and departure time. According to the kind of tickets purchased, there are different deduction amounts for passengers’ accounts. Please remember the following if you need to cancel a Turkish Airlines flight reservation.
Travelers who purchase a Refundable Ticket will get a refund once cancellation charges are subtracted from their original ticket value.
A non-refundable ticket may be eligible for a refund (taxes) in exceptional cases. Still, the passenger who bought a non-refundable ticket will not receive a refund in the majority of scenarios.
