Good but need to be better with the flight times.

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

The airplane is way too tight, you can hardly enter into your row to sit.. more like kids seats than adults.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

Flying with Air Canada is still better than the discount airlines like Flair. The seats are more comfortable and the on-board entertainment is better, with each seat having a built in screen and lots of content to watch. Onboard WIFI is also great to have, as well as plugs for charging. I think passengers in general are getting better at not bringing too much luggage onboard, and Air Canada is better at managing this without customers feeling like they are being taken advantage of with extra fees. I have travelled on different airlines and all seem to be loading faster, with fewer people bringing both a carry on and a personal item. Now I just bring one item and it fits under the seat so I don't need to worry about finding a place in the overhead bins. Overall, across the industry, asking customers to pay for carry on baggage is fair because it allows customers to only pay for what they need, and it helps to keep the planes on time. Kudos to Air Canada for its approach - the desired result is achieved without customers feeling that they are being surprised and caught with unexpected extra fees.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

Due to the strike by AC flight attendants, my flight was cancelled. Very disappointing! A refund is being processed. This was not a Kayak issue. I will be sure to come back to Kayak in the future.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel
