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.

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.

everything was excellent except for the meal on the fight from the Istanbul which was disgusting, the only choice of food available was pasta which was served frozen.

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

This was my third time using Turkish Airlines. I was well satisfied with the overall experience! I believe that no one is perfect and that everyday we are trying to do the best we can to help others by giving a part of our lives through service. I believe from what I’ve seen that Turkish Airlines, have come close to that service! I will definitely recommend and reuse their services again! Thank you!

Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

Turkish Airlines is a solid airline. They use the less trustworthy Boeing airplanes on this route (VCE-IST) so the flights more bumpy then when I have flown on Airbus planes, but it was okay. The service good. They seem to offer a reasonable selection if movies, although no way to listen to them as they didn't provide me earpieces. The food was surprisingly good. The day was uncomfortable. The flight was on time.

Food and crew were superb. I flu with a 777 which has old TV screens. Although the movie selection was very good, screen was not sharp enough to wacht a movie

Poor connecting flight logistics and ground transportation for such enormous airport. Airline does not consider time required to complete the security check or transition from one to gate to another

Food wasn’t good but not their fault as I should have pre selected

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

wifi was iffy at best. Movie selection could have been better

Boarding was chaotic and confusing. The seats were so close to the row in front that my knees were up against the seat in front of me the whole trip. The beverage service consisted of a small plastic cup of warm water. This was truly a very bad experience.

A basic, cheap flight from Bucharest to Prague. No Frills, but we got there safely.

It was cancelled you imbeciles! And then you have the gall to ask for reviews? Here! Have this review, you damned cretins!

Upgrade to business was great. The crew was nice. Disembarkation in Bucharest was very slow through the rear door to a bus to get to the terminal. The business lounge was not clean with bugs running on the floor.

I rated food and entertainment with the lower score because I did not have N/A. No food and entertainment from Bucharest to London.

Poor service ! Water need to be free and a little snack for 3.5 hour during the flight. Tarom company need to take lessons from Turkish Airlines.

There was extreme turbulence for 10-15 minutes a bit after takeoff, which of course is no one's fault. This was a short regional flight with no amenities except water. Departure and arrival wete close ro on-time. The Suceava airport is very small but pleasant and efficient. My baggage all the way from Washington DC, checked through Paris and Bucharest, arrived without a hitch. There was really nothing to complain about except a regrettable 5+-hour layover in Bucharest.

This experience was atypical. The flight left three hours late because of engine technical issues, which meant a very long wait. Unrealistic announcements made it worse by discoursgong leavimg for water, reatrrom, etc. But the crew did its best and apart from the delay, it was not a bad flight. Good entertainment and drink service.In the end, I made my connection anyway.
