temperature during flight. Freezing then hot, freezing then hot and never a comfortable temp. Food was terrible. Entrees were flavorless and smelled terrible. Time they served food made no sense at all either. Within the hour of getting on the plane, they served a meal which made no sense because most folks ate before getting on the plane. Stewardesses were not friendly (only 1 made me feel valued and welcomed)

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)

The flight was operated by Air Canada, who habitually assume either that the people in the final row have no hand luggage or simply suffer from a severe lack of operational storage capacity. Overhead bins full of spare plastic cups. As far as the crew are concerned, no problem, because you can just push your way three or four rows forward while everyone else is boarding and then take someone else's overhead space. When will Air Canada learn how to run an airline?

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

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.

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.
