Older plane with finicky seats. Crew often seem to focus on "pet" clients and over extend services to some over others. I get less attention since I'm not a regular business class client. Regardless, I've paid the money and would expect equal attention.

Older plane with finicky seats. Crew often seem to focus on "pet" clients and over extend services to some over others. I get less attention since I'm not a regular business class client. Regardless, I've paid the money and would expect equal attention.

Our flight attendant was stellar with great anticipation and attention to details. Food was very good, and overall flight, though very long, was really good.

Be honest of what you sell: This was sold as Business Class on all three legs, while the JetBlue plane didn't even have business class seats, and wanted $164 for extra legroom seats.

Great food, and lots of it. They made us come to the gate two hours before the flight and you were stuck in the enclosure until you boarded with no bathroom or food or drink. My seat in business class was very claustrophobic, I could barely get into it and a large board blocked the window and made it even more claustrophobic

Turkish Business Class is a wonderful experience, and the best inflight dining experience I’ve had to date.

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.
