Older plane, uncomfortable seats, no individual entertainment systems. Long boarding without a lot of staff facilitating extra coat/overhead luggage storage because of winter, then we sat on tarmac for two hours because they missed their slot to take-off.

Flight to Istanbul was fine. The flight back was a terrible experience! During our connecting flight in Athens our boarding passes wouldn't print at the self service computers and there was no one to help us so we had to go back out to the front desk. The airline representative was extremely rude. There was 5 employees standing around the computer with NO customers and when we asked if this was Turkish Airlines and if they could help, the woman (manager) responded "this WAS Turkish Airlines" as if they were done helping customers for the day (it was 9AM and our flight was leaving in 45 min). We explained that we couldn't print our passes and she ROLLED her eyes as if it was an inconvenience to help us. THEN on our flight from Istanbul to Chicago, a passenger died an hour into the flight and they placed the body on the seats behind us for over 10 hours! Nobody even told us what happened! We didn't know if they died from natural causes or if it was something else! They didn't offer to seat us somewhere else or even inform us they were placing the body there. We were completely shocked and uncomfortable the whole flight home. We couldn't eat or sleep. We're completely disgusted and scarred from this overall experience.

Flight was delayed by 5 hours and customer service in Istanbul consists of assholes who don't know much about customer service. They gave me their printed policy on flight delays and refused to do what the document requires them to do. I was one of the well treated one! They are bastards.

The flight to Lviv was cancelled after 3 hours delay. All happens in life. But the only option Turkish airlines were offering is to fly the next day. I was flying to the funeral and this was not working for me (especially this was their second flight to Lviv cancelled - 2 in a row). The transfer desk didn't inform that there were two other flights going the same day of other airlines. When i approached to help me to go with a different airline the personal was very rude saying they will not help transferring the luggage and that they can't unload the luggage sooner than 3 hours after you go out of the security and passport control. When i asked to book to a different destination in Ukraine. It took 50 min at the desk to do it. Simply because 4 people at the desk were laughing and joking and nobody was concerned about the queue of over 40 people staying. After 30 min it turned out they've lost my boarding pass and it took 15 min to find it as one of the transfer guys managers simply took it to a different room... At the end when they found it it took only 5 min to do the work. I would appreciate more information from the desk about available flights and more support to manage the situation. I'm happy that people at the transfer desk are so joyful and happy it obviously helps to deal with the stressed passengers whose flight was cancel.

Excellent crew-seats were decent-not as good as Emirates., but doable. Seats from Frankfurt to Bengaluru in India were smaller than US domestic airlines-a feat thought unachieveable!!

Food was terrible-choice for dinner was Salmon or pasta with tomato sauce! Obviously picked the salmon which was sitting on a bed of soggy rice and a dinner roll that was so cold, I could cool my drink with! It was also hard enough to use for self-defense. The entertainment system was so bad, the kid behind me was punching the screen!! It took me 5 minutes to wait for the screen to respond and it was not much larger than my phone. Again, miss Emirates-this will be my last flight on Lufthansa!!!

I liked that if I asked for something the crew would get to me rapidly. Extra leg room.

Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!

When I missed the flight in Brussels I had no options re: changing my ticket as there was no ticket sales counter at the airport. Had to go to the travel agent and book a flight on another carrier.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
