Turkish Airlines offers flexible options for passengers needing to adjust their travel plans. If you need to modify your booking, the change fee varies depending on the fare type, route, and time of the request. Generally, economy promotional fares have higher change penalties compared to flexible fare options. It's advisable to make changes as early as possible to avoid additional costs. The Turkish Airlines change flight fee may also differ for international and domestic routes. You can make changes online, through the mobile app, or by contacting customer service. Always review the fare conditions before confirming your ticket changes.
