The flight was very bare bones. Entertainment system froze up half way into a movie. You had to pay for wine with dinner. Even on budget carriers, wine is included with meals on the long hauls. Half a cup of water was served twice during the flight. The cabin was kept quite cold. I wore thick socks and slippers throughout the flight, but had to use the small blanket provided to keep my feet warm. Glad I had a heavy coat! I will avoid this carrier on any long hauls in the future.

Dinner not too good. Breakfast very poor. Cold flight. Entertainment not working. Avoid for long hauls.

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!

I loved that the trip was relatively short and uneventful. The food was adequate, but nothing to brag about and very little. The hostesses were nice,better than last time. The price was right on, mostly for a trip of under 15 hours...when usually it is 20h with a stopover.

On the way over, I couldnt get water. The trolley didn't come by, and I had to "leg-over" my sleeping neighbor to get a glass of water fo the back reserve. The TV wasn't working; the remote was dead. As it was a night flight, it didn't matter tt much for me, but it should've been working. The passengers could have been spread out better as there were completely empty middle rows. It would have helped with comfort.

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!

We were told over the phone that we could bring our kayaks with us to Africa but the airport staff denied not only our kayaks, but also our paddles which were in a standard ski bag. Their excuse was that both the kayaks and paddle bags were 2 inches too long. .. TWO INCHES!!!!!! We had record of the person we talked to and the time and date, but none of that seemed to matter. It caused A HUGE INCONVENIENCE for us since we are in Zambia for 6 weeks without our gear to paddle one of the most challenging rivers in the world... the Zambezi. Now we are constantly trying to acquire the proper equipment with very little success. We run a nonprofit called the Montana Kayak Academy which provides free whitewater instruction to youth between 8 &18 yrs old and we will be sure to tell everyone we know to NOT TRAVEL WITH EITHER VIRGIN ATLANTIC OR BRITISH AIRWAYS.... EVER!!! VERY DISAPPOINTED! !!!!!!!!!!!!!!!!!

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.
