Excellent 10.0

Pros: Seats were super comfortable, bigger than most planes with extra leg room. Food was excellent and fresh, amazing Dutch cheese sampler was divine. No nonsense staff who had all connecting flight info on hand when we arrived in Abu Dhabi. KLM staff were friendly and efficient. Fabulous airline.

Excellent 8.0

Cons: Service desk personnel at the gate were very helpful and attentive. The plane was only 1/2-2/3 full, which made boarding quicker. The food was tasty and coffee was great! We were also offered juice twice during the flight. Bathrooms were clean. Since the plane wasn't full, they weren't dirty even at the end of the flight. I brought my own headphones, but the stewards provided them if you need them. My one big complaint was that our seats did not recline, thus making any kind of shut-eye near impossible. Our plane left and hour late, but the pilots stepped on the gas and we got in on time!

Mediocre 2.0

Pros: They had very bad service for 5 hours flight I asked two times I need a coffee but they didn’t give it for me and on that time I saw they serviced for two another guys just they said to me “we come back to you” but unfortunately they didn’t come back. No facilities for calling the crew. I am very angry for my flight Toronto to Vancouver specially the bad crews.

Cons: See and train the crew and look for your services for 5 hours flight.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

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.
