Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

The food was great. The seats were soft and there was enough legroom.

We were stuck on an aisle where the seats don't adjust on one of the flights, but it was a relatively short flight. The boarding process was a little disorganized, but we were able to get on the plane quickly. The worst part was the home airport. I don't know how much control Turkish airlines has over that airport, but the bathrooms we're absolutely disgusting.

Flight was changed from what was originally scheduled and purchased. I was informed of the change after the purchase before traveling. Thus I had 4 1/2 hours between flights.

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

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.

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.
