First of all, my flight got delayed. When I had a registration in Astana, the girl who was working on a desk was too lazy to fill out my info and that’s why she gave me only 2 tickets instead of 3. While boarding I realized it and had to talk to another worker who was solving this problem. My seat was near emergency door, people in front were reclining their seats, but I couldn’t- that made me have a little space to sit, move, etc. That was really uncomfortable. So the flight itself also took longer and I didn’t have time to reach another gate for next flight, even tho flight attendant said plane will be in time. I had to go to Turkish Airlines main office, most of workers didn’t speak enough good English to explain properly where it is. It also took me like 1,5 hours to solve. I was not satisfied with the flight at all this time.
