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.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

Original Lufthansa flights were canceled and the alternative route that was offered required cab transfer in New York from JFK to Newark at my own expense. Who can refund these $218?

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

flight was packed, had to check my carryon bag, tiny snack bag offered, but we arrived on time and thats what counts

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.
