My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

It was great! Great value for the price I paid. Great crew and great food in business class

Everything was so smooth. It could be just a better temperature in the plane; it was a little cold.

Turkish Airlines will be my first choice to fly in the future.

On the Boeing 777-300 aircraft there is no personalized climate control for passengers. Every time I've ever flown on this type of airplane I've been uncomfortably warm. For shorter flights (less than 5 hours) this isn't a big deal, but on longer flights where a nap is required to stay comfortable it turns into a nightmare. I love turkish airlines, but I really fo hope they upgrade their fleet. I've flown turkish air once on a newer model and had a fantastic time, so I think its the plane more than the airline.

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

Staff friendly. Business class but issue with flat bed. Incoming Turkish flight delayed. Made connection due to fast buggy but luggage did not make it. Confusion at Delhi airport

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens
