Getting our bags through on a tight connection - great job Staff were helpful in finding a safe place for my bassoon.

inability to select seats without having to pay vast extra amounts of money is totally unacceptable. Ended up initially separated from my daughter and then on seats that did not recline. Flight left three hours late, nearly missed connection Next tine will fly Virgin. They look after their passengers!

Boarding process was very orderly. The 2-4-2 seating arrangement is quite nice for economy as it is a bit more spacious & comfortable. Sat in window seat with a huge compartment storage next to me by window - great for easy access to electronics, etc.. Great movie selection. Short and efficient flight and my fears about basic economy ticket were dissipated as I was able to check a bag and get better seat assignment at airport.

Slow service, not served dinner until almost 10pm. Lights were never turned down so difficult to sleep altho I had eye mask and noise cancelling headphones. Seats are not super comfortable but if you bring neck pillow and blanket it’s better.

Three hour delay, endless gate changes and basically no information shared as to what was causing all the problems. Don't think I'll use Air Canada again if they can be avoided.

Roomier seats overall, the headrest screens and USB ports are great!

We paid extra for seats with more leg room and got the same as everyone else. Why the charge? Our departure was delayed. The plane had some sort of fragrance regularly coming thru the ventilation that irritated my sinuses and made me ill. The water for the only service on the flight (for coach anyway) was warm and tasted odd. Cabin temperature was too warm (multiple logical arguments can be made for cooler temps over warmer)

No information about the delay, no vaucher not excuses. Crew non existent during the flight compared to Asian airlines. Food was so so and not the greatest way to come home.

We paid extra for seats with additional leg room and knowing the first row of these is at a wall with no room for feet with legs extended, we requested a different row. We did not get this though we were told we did AND paid for it.

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.
