We had lots of seat space because the flight wasn't full and we could spread out a bit. If the plane hadn't been full, the seats and leg room space were insufficient. The food was good. The on board entertainment was enjoyable, making the time go by quicker.

We weren't able to select our seats, they were selected for us. We also couldn't print out our Boarding Passes until we arrived at the airport giving us an uneasy feeling about the seats we would be assigned. Ultimately, our seat assignments were fine, but no need for the drama.

The crew was pleasant and accommodating to me, my wife, our 3-year-old and 1-year-old for both legs. The planes were in good shape and everything was on time. The balthrooms were clean and felt spacious. I didn't eat the dinner because we ate a large dinner before the long flight. I did tasted it and it was good. The selections of movies was also very good.

Thw system they use for in flight entertainment was a little glitchy.

I liked the fact that the customer service on board was pretty spectacular & very clean bathrooms.

It was extremely warm throughout the flight and the seats weren’t too comfortable.

The food on the flight was good.

The wheelchair assistance was very bad as no one turned up with a wheelchair. The airways really need to improve their service and make sure that whey they offering wheelchair assistance they in fact do it. This has happened serveral times that no one turned up at the London airport.

I had to change my return ticket early because of an emergency and Air Canada charged me $481.00 whenI only paid $371.00 fora round trip. How is that possible?

Compared to the flight going the other way, this one was much more comfortable. I didn't have someone's seat back in my face the whole time, and was able to enjoy games on my own device. I like that both USB and normal power options were available, so I was able to play games and charge my phone so I could use it after landing. The food was passable as well, which was surprising.

It's unavoidable when flying between multi-lingual locations, but having movies and stuff pause three times for each announcement gets annoying. The rolls served with the meals were very dry. These are small nits, and the flight was generally enjoyable.

I love the variety of entertainment, it never fails.

I didnt like how snacks werent included for my 6 hour flght. Also the amount of waste made with all those plastic cups is astonishingly ridiculous. Switch to a more green solution!!!

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.
