The Bus carried all passengers to the plane . There was No help or assistance available for Handicapped passengers We had to climb the stairs. The person in front of me had Only one leg to stand on and was using crutches to climb the stairs This was like a survival of the fittest test and a horrible Experience. The Airline should provide assistance at the Boarding stairs.

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.

Equally friendly crew and experience. It was complimented by the time we got to spend in the fantastic KLM lounge while we waited for the flight.

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

Crew was great. Good selection of movies too.

The flight itself was fine, but what has been a horrible pain has been trying to get refunded for an accidental double booking.

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
