Boarding made sense. They boarded the back of the plane first. Kudos for that.

The seat cushions were nonexistent. Less legroom than a mini backseat and no way to upgrade since I purchased on kayak...unless I was willing to pay $4000 more to get premium coach seats. Will not use kayak again.

Okay 4.0

The cabin crew were pretty good. That's about all that was good.

I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again.

Everything went okay for us on this flight. In the future, I will suggest to my wife, who books air travel for us to read the fine print. The cost to check a bag was $100.00 which would have run us $300.00 for the trip: Boston to Brussels with a layover in Reykjavik, but on the return Brussels to Reykjavik with four days in Iceland and the return to Boston, so there goes the cheap flight! I did enjoy the in-flight movie and a documentary on the return trip as well.

My own earphones on the flight from Brussels to Iceland did not work. I could not plug them into the system.

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.
