Excellent 10.0

The new plane was amazing and I feel so fortunate to have had the opportunity. The experience was streamlined and the technology state-of-the-art, accessible, and extremely useful. The impressive crew looked flawless and performed their duties very well. It was all quite a spectacle!

It is always really nice to get free coffee as a passenger. Traveling is exhausting and I would have been so appreciative of free coffee on the flight, and felt even more comforted and likely to fly Norwegian in the future.

Nothing

I never got informed, neither by the airline company or booking company that I had to order my meal 3 days prior to the flight if I wanted to be served a meal. Paying for tea or coffee is just outrageous. Crew does a minimum requirement and isn't even nice when you are just asking for a glass of water once throughout the entire flight.

Nice, clean plane.

1. Flight attendants except for a couple, were not interested in helping passengers or answering questions 2. For the basic fare (which I didn’t realise I was even purchasing), you had to pay extra for a seat and for luggage, on long haul transatlantic! 3. I wasn’t offered food or beverage once on the 8 hour trip 4. You had to purchase a blanket if you wanted one. Everyone was wearing their coats onboard. It almost felt like they were intentionally keeping the temperature cold to induce passengers to purchase blankets. When I requested they raise the temperature, I was told that this was the warmest they could make it and this is the warmest on any plane. (Obviously not true. I fly every month and have mostly found plane temperatures to be manageable.) Oh, and did I mention how you had to pay to check luggage on a transatlantic flight!!

Flight crew was pleasant and attentive. Seats were comfortable for economy as well. We were allowed to check in extra baggage for free at check in which really helped since we would be catching a connecting flight in Amsterdam

If the format is ordering food there's suppose I be a good standard of service. And there isn't. Also they didn't have earphones for sale-- if they're not handing them for free st least make sure you have some for sale.

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

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!

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.
