The movies and entertainment offered in the screen were alright.

We were delayed over an hour because flight got in late from Halifax, I get it, stuff happens. Then once boarded we sat there for another 45 minutes. The pilot comes on over the speaker and explains we aren't leaving because the crew didn't have the proper paper work in the cabin...

Everything was good

One Stu artist who was a older women she was very grumpy, there was little to no turbulence the whole flight and if you got up to go to the washroom and we’re waiting and seatbelt light came on she would make u sit down immediately even if it wasn’t that rough, she made a girl wait for the washroom for 45. Minutes was kinda pathetic, when she was on her shift break not one person had a issue with any of the other flight attendants only her

The extra $50 seats were roomy.

Flight was delayed and no one knew why!... Plane had been sitting ready at the airport for hours. Novice flight attendants, they each picked on different things others missed just before them. No consistency, seats left reclined during takeoff and landing for example. One way there was drink service once even though it was a smooth flight and the return had drink service twice even though it was bumpier! Entertainment does NOT work on androids, it is NOT the AirCanada app they tell you to download prior to the flight, it's an AirCanadaRouge.pk file that needs to be downloaded in flight! Which means we're stuck paying for the iPad and of course only with cc because there's no wifi for debit cards.... AC needs to stop this insanely mediocre and yet expensive monopoly.

I think the air quality on the flight from Toronto to Seoul was bad. I felt really neaseous for most of that flight and thought I would be sick on the landing. the illness went away completely once I landed and I didn’t experience it on the Asiana flight from Seoul to Phuket

There is nothing to like about Air Canada anymore.. unless you happen to like the abuse and indifferent service. Employees seem disengaged.

AC used to be mindful or customers with connections. This is the reason I booked all segments with air canada. Found out the hard way it is no longer the case. Lesson learned. Missed connection and ended up on stand by for the next flight ( no more protected seats folks). Was not even refunded the money paid for seat assignment on the missed connection.

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.
