Is it necessary for you to modify or change the name on your Turkish Airlines ticket? The services for name changes and ticket adjustments are governed by Turkish Airlines Name Change Policy. According to this guideline, each passenger's information must correspond to the information on their other official documents, such as their passport and visa. Everyone is permitted to modify their name data up to 4 letters for free within 24 hours of booking in order to make compliance with this guideline easier. However, following this time, a specific fee is assessed based on the ticket and class type. Both offline processes such as visiting the office or phoning the support line through an online method through the webpage can be used to change a person's name.
