I fly with TK regularly and I have concerns about their safety, despite a number of serious incidents I find their pilots very gung-ho in bad weather, I watched what I assume was the walk around when the pilot came out for a cigarette and a look at his phone, barely looked at the aircraft at all.
Crews I have found to be very enthusiastic and willing but never fill me with confidence. A few weeks ago aircraft took a detour around IST, passengers got bored and started getting up (this was when aircraft was taxiing not just rolling the last few meters to the stand) and crew said not a word.
So I am not suprised when I hear of new incidents involving TK.
