I've been buying tickets here for many years now. The staff is polite and works quickly. You can also buy tickets remotely. Prices with the central ticket office do not differ. Unlike the central ticket office, there are no queues.
I'm not wearing this ticket office
I bought a ticket to Frankfurt with a transfer in Istanbul. When registering, I asked about the fines for postponing the departure date. The employee assured me that there are no fines and you only need to pay the difference of the ticket.
I bought the ticket on July 2. When reissuing the ticket for the next day of departure, it turned out that Turkishairline imposed fines from July 1. The notification to the ticket office came on July 7. And they made me guilty. It is unclear why the customers were not notified...
There are two jocks sitting at the entrance, if you raise your voice, they are ready to break your nose... They introduced themselves as guards.
