We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Terrible - we needed tp change the flight and it was impossible. They ask for a price that was higher than buying a new tickets from another airline. Will never flight Swiss air and Luftgansa again.

Zürich to Boston was great. Nice to Zurich was not bad

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

The meal was wonderful and strawberry ice cream was a plus.

Absolutely amazing! Best airline i have flown with, huge difference to United!

The best airline for international travel in terms of value you get in business class (service/cost)

Boarded via bus instead of the air bridge Had to wait 10mins in the bus at the tarmac before we were allow to go up

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

THE SEATS ARE A JOKE!!!! YOU CALL THIS BUSINESS CLASS SEATS ? ITS A DISGRACE.. NARROW, CLAUSTRIPHOBIC SEATS CAN NEVER BE COMPENSATED FOR BY FOCUSING ON BETTER WUALITY FOOD SERVED....... THE CONFORT OF THE SEATS AND THE WIDTH & PITCH OF THE SEATS ARE WAY MORE IMP. THAN FOOD THAT TK IS FOCUSING ON... WILL NEVER FLY AGAIN EVEN IF THE PRICE OF BUSINESS CLASS SEAT IS SAME AS ECONOMY CLASS..... JAL/ QATAR/ EMIRATES HAS WAYYYY MORE COMFY SEATS

The entertainment center of my seat wasn’t working. I asked the crew many times to restart it and they that will be done by the next crew that take control of the flight in São Paulo. Bad attitude during the whole flight

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

good entertainment package but rather small seats for business class

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

Business class was roomy and comfortable however, the entertainment screen was very dark and hard to see.

Great experience, flight was on time and reached on destination on time .. very accurate and smooth experience

The entertainment screens need to be updated. Very difficult to navigate through with old equipment.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

I came out early, 4 hrs before departure. The flight was changed 4 or 5 times with few minutes between new and schedule time , then 30 minutes delay, then up to 2hrs 30min delay. When I arrived in Frankfurt, no one help us to lead to the custom service. After almost 1 hour asking around then we must line up for another hour to get overnight and rebooking the next flight. We must find out how to get to the hotel by us self. The shuttle bus driver in Germany was not nice, speak German to English speaking and we must predict what she / he tried to tell us. We got up earlier and tried to not coming late to the check in and immigration procedure (we were told by the helping center that the immigration used to be over crowded) then we came there it was almost empty, then we must stay in the airport for hours not necessary. We got the coupons at the airport for compensation for waiting for delay flight for NOK 75 ( as low as 6 Euros) It is not enough to buy food at the airport price and Norwegian cost of living... How to drink a cup of cappuccino for NOK 72 when the stomach was empty for food in 16 hrs (from dinner at 6 pm the day before to 16 pm the day after) At the hotel in Frankfurt, we were offered two options spaghetti with biff or vegan food and a drink for 18 Euro. Almost 60 passenger ate the same food and I was remembered once time in former Soviet Union in 80's I travelled with Aeroflot and the passenger were stranded in the hotel for next flight and we were also offered only one choice of dinner, if we were hunger we must pay 1$ for 1 egg and another 1$ for two loaf of bread and butter. I can't believe Germany is to poor and inferior service like former USSR in 1980 decade. My good remembering of Luft Hansa disappear and changed totally by this service I got this time.

Did not fly to Houston as original flight was cancelled.
