The economy seats are more comfortable than average transatlantic flights on other airlines, albeit far from perfect. The meal was nicer too. The crew both onboard and on land was nice and attentive.

The entertainment system is slow and the selection of films to watch could be better.

British Airways overbooked this flight and made it unclear if I can board my flight. Overbooking is such a greedy behavior and airlines should refrain from engaging in this dubious policy. It is the second time this happens to me with BA.

My seat was comfortable, with good head and neck support.

BA doesn't allow guitars as carry ins, unlike most every other overseas carrier. That's a major negative for me, and I've spread the word to other musicians who will avoid the company. Terrible policy.

Brand New plane. Great German entertainment. Crew were very efficient but didn't show up with drinks as often as in the past but still more often than other airlines. Overall a wonderful experience.

Took two hours to start dinner service without a reason. Turbulences and a passenger with long legs were impeading my sleep but not Lufthansa's fault.

It was late both going to Prague and coming back. Then on this flight the stewardess tried to tell me that I could not put my bag on the bin on top of my head - she was reserving it for other passengers! Then she realized that her comment might sound racist (so she apologized), then she told me that I could not put my small bag under the chair. Finally I told her that she is certainly looking for a way to get me off the flight to which she answered "I can certainly find something!!!" Cultural sensitivity is needed with these stewardesses who are racist like I don't understand and I was certainly polite!

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

When I got to check in at the airport I found out I had to pay $100 per bag. This was never told to me when booking. I was also made aware that if I had booked my bag when I checked in on line each bag would have been 75$ . Of course I hadn't checked in on line and this was a huge surprise.

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.
