Very good. I was happy that business seats were in a 1-2-1 configuration for the long haul flight. The shorter flight was a 2-2-2 configuration which I do not like as much, but it was a 3 hour flight that I slept through.

Very good. I was happy that business seats were in a 1-2-1 configuration for the long haul flight. The shorter flight was a 2-2-2 configuration which I do not like as much, but it was a 3 hour flight that I slept through.

The crew was amazing and the food was really good too

Some of the best service I’ve ever seen on an international flight! The staff were super friendly and accommodating. The food was excellent with lots of choices and attention to detail. The seats are kind of old and narrow, but I have wide shoulders. The only area for improvement was making the cabin a little cooler.

It was fantastic. I really enjoyed it. It’s comfortable the flight attendant. Respect you anything you ask for they gave you except the water.

We were experiencing delayed for 4 hours and of course they took us to Turkish airlines lounge but we could not rested up since there is no bedroom. It was tiring and long day for us🙏 Especially we didn’t fly until 5:45am morning for Miami🙏😢

On Turkish it is all about the food and the service. I am overwhelmed with the quality and variety of the dining service offered on business class. I prefer the updated A350 to the older B777 cabin layout, but both are comfortable. Flights left and arrived on time with updates from the captain. I will definitely fly with them again.

Seats paid for in advance. Seat assignments changed by kayak 3rd party. Seats then changed again by Turkish airlines at the gate. Family seated on opposite sides of the plane yet money taken for seat assignments that were not honored.

The boarding was not as organized as what I experienced in Houston. We were able to depart on time and landed in Lagos as scheduled.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

Turkish Airlines lost my reservation!!! I had to wait 8 hours for the next flight. They provided me with no food no water. Completely ridiculous!!! Never fly on this airline.
