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.

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!

Really good price, excellent service.

A silly point, but I would appreciate fewer announcements when I’m watching a movie. (Laughing out loud)

We traveled with our 11 month old and the crew was super helpful. It was an 8.5hr flight, we got a middle seat to give him space to play and the staff had a lot of fun engaging with him. They even gave him a couple of toys to play with. Food was just ok, but better than most airline meals I've had. We flew Premium Economy which was a comfortable experience as well.

Checking in took too long, but that's more due to the new US-bound flight restrictions and process that's supporting that.

Food was good and so was the entertainment on board

Issues with boarding due to problems with brakes so flight was delayed by 3 hours. No food or drinks were offered

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!

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.
