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!

On the MSP to ATL leg the gate crew made a huge deal about checking rolling bags. They even stopped us at check-in and nearly begged us to check our bags pointing to the backed up jetway. But we had a lot of unpacking to do before checking our bags so we politely declined three times. On getting to our seats there were at least 8 open slots for bags near us. I heard a crew member call forward to say "tell them no more rollaboards" so they forced everyone left to check. On departure they slammed shut several very large empty overheads. WTF

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
