Pros: A340-600 is a wonderful plane, but economy is too cramped. The stewards do their job of feeding the "cattle", which lacks any personal service.

Cons: The terminal updates of terminal and gate notifications were wrong! If we had followed your email and gone to T3, we could have missed our flight and be worn out from changing terminals.

Cons: I paid $100 extra for extra leg room. I was put right next to the bathrooms. All night long people were standing in line to use the bathroom. My extra leg room was taken by people standing in the space and actually stepping on my foot. Not worth the extra $100.

Pros: It's a direct flight.

Cons: Everything - the plane was last updated in 1989 (you can still see where the cathode ray screens were bolted to the central overhead bins), the entertainment is laughable, several didn't work - passengers were given choice of putting up with that or getting off flight. A flight to endure, not enjoy

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.

Good 6.0

Pros: Decent service.

Cons: I paid 100$ for my seat, for more leg room. It happened that the seat next to me was unoccupied. I thought it would give me an opportunity to stretch out a bit to sleep on the Atlantic crossing. Another passenger's tv didn't work so one of the stewardess told him he could sit next to me. He got more leg room for free. I was cramped and could not sleep because of muscle spasm. The Legal age made it more comfortable but it is not worth 100$

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.
