I am at IST now. It was my first flight on TK. I must say that I am really impressed. The amenity-kit for CC as good if not better than AC's J. seats are bigger than what i expected judging from TK website photos and they are Similar to the old J seats on UA, CA, TG etc, but the leg rest part make them more comfy. food was better than regular Y and the IFE was great. Lots of choices and no commercials.
For the price that we are paying for this fare, it is just fantastic lol^
