Crew was very friendly and helpful when needed. Excellent choice of movies/entertainment (for my personal taste). Overall a pleasant, smooth 7 hour flight.

Food was as decent as an airline meal can get. Seats were as comfortable as an economy class seat can get.

The food and plane was good

We got stuck on the plane for an hour and a half after we landed because they couldn't get the ramp set to let people out. This was after a 9 hour flight.

Low price, new smart aircraft, comfortable journey in Premium, excellent service from the crew.

In-flight entertainment very limited. Not many movies, strange tv program content, no music at all. The flight was late leaving Oakland and the pilot didn't make up any time, so I nearly missed my connection in Stockholm. Aalanda airport was part of that problem as transfer security had a single line with one really slow person manning it! That all added up to a long line of very anxious travelers!

entertainment ok

did not know that they charge extra for everything. 7 hr flight and they don't even give you a glass of water without charging you extra.

Flight crew was pleasant and attentive. Seats were comfortable for economy as well. We were allowed to check in extra baggage for free at check in which really helped since we would be catching a connecting flight in Amsterdam

Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess.

I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly

Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in 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!

The new flight procedures informational film at the beginning of the flight (BA/Comic Relief)

The flight was to Heathrow which was not prepared to accept us at all. We waited 45 minutes in passport control. I expect BA to make sure the port of destination is prepared to receive its passengers

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,
