Flight was on time and I received my checked baggage.

Seat was uncomfortable due to insufficient foot space. All (about 6) overhead bins in the rear of the aircraft were full because crew stored “essential equipment” in them. Crew was not professional. After takeoff they never came around to see if anyone needed anything and not even a glass of water was offered for the entire flight. They didn’t even ensure that everyone wore seatbelts on landing - woman next to me was stretched out hugging her companion while landing wilth unbuckled seatbelt. Entertainment screen did not wirk properly.

The crew was very rude, I was told I had to store my purse, the person next to me wouldn't store the carry on baggage, I needed to take scheduled medicine in flight, I couldn't as my purse was stowed. I was delayed for over and hour and a half after arriving. I had to stop and eat in the airport. With chronic health issues addressed this way I will probably not use United again.

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. Also, really tired of the fake business class on these flights...

Seats are very tight and uncomfortable. The food was horrible. Tasted like a $1 frozen meal that was microwaved til mushy. It was chicken but I couldn't tell you more. And flight attendant helpfully described it as 'chicken'. Breakfast was a cold roll, a piece of cheese and some awful yogurt. This was the most unbearable 8.5 hours of my life.

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

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.

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.
