Both of our Business Class seats were broken. I'm sure they didn't just break before we boarded but were broken prior. They would not recline. We could sit up straight or lie down, nothing that would allow us to sit back and relax on a 12 hour flight. Totally unacceptable. Very expensive and a waste or money.

Turkish Airlines lost my reservation!!! I had the ticket, the receipt and they lost it!! Because the flight was fully booked, I had to wait 8 hours!!! Turkish Airlines provided me with NO FOOD, NO WATER!!! Absolutely ridiculous. They were pathetic. They admitted it was their fault for losing my reservation but provided me with nothing.

Very comfortable in business class. Excellent service. Good food. Smooth trip.

had to wait 1 hour once boarded. so we were 1 hour late arriving.

The crew checked the immigration laws very quickly for Russian citizenship and confirmed our FVTF for Singapore for 96 hrs. Thank you.

Went great, they even reopened the gate for me when I arrived late.

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.
