I'm at IST right now. I came in on TK 4 from JFK. We were not diverted. The crew made no announcements about the attack during the flight and said nothing after we landed. Just the normal "we hope you enjoyed your flight etc..." If I hadn't checked my phone i'd have no idea. The int'l connections area was a mess. Huge lines, people stranded. Absolutely bo one from TK around to let anyone know what's going on. Half the flights on the board are cancelled most of the others delayed. I got up to the lounge which was closed for a while before finally taking pax in. Again there are ZERO TK staff here who knows what's going on w flights. It's a complete zoo. For now my flight is on the board.
