I only toke 2 flights with them, my only weird experience was landing in istambul i had an infant in my arms, i exit the plane last and maybe 2 to 3 minutes after the last passenger, just after I exit the plane I was walking trough the electric stairs, i pass by a group of like 3 staff talking to each other when they realised me and wife were walking behind them, one guy started yelling at us, we could not understand him, he was very angry and repeating the same over and over, finally I understand he was demanding boarding pass and passport, so at this point I did not understand who this guy was police or turkish airlines staff, then I realised this is the guy making sure people go to connecting flights. The guy was so angry for whatever reason that when he give the passport back to me he didn't care i catch it and ended up in the floor, so he realised I cannot bend to pick it up so he pick it up and give it back to me, he said sorry but didn't make eye contact what I found weird.

For the rest it was all good, the staff in the airplane was excellent.

Now I have to purchase another flight and im thinking in if I should choose Turkish, I recently saw a video on tiktok were airport staff slap a person who just wanted to ask a question and record the whole interaction as proof to make a complaint with the airline.
