Airline reviews

Very tight seats - no legroom at all, very tight to the person in front of you. If you have basic fare, you are loading zone 6 regardless of where you are sitting in the plane - meaning even as a middle aisle person at the front of the plane, I had to get people to get up and let me in as they had boarded earlier. Having to pay for a carry on is criminal. I am a frequent flyer, and air Canada has now joined the list of other terrible North American Airlines.

The crew was amazing! I was a bit surprised and disappointed that there was not wifi available for personal use. The only thing I would change would be the seat cushions. They are not comfortable at all for long flights.

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

I travelled in Business class for the first time and wish I could do that again.

I like the free air Canada wifi and being able to watch things on there. The basic snacks are good, just wish I could have both. If I’m being really picky, the flight attendant who filled my drink, filled it half with fizz and didn’t take the second to let it go down and add more, so I got maybe half a cup of pop.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

On board wifi or other entertainment. Landlines option was good but ran late to Pearson

Flight was fine and on time. But no entertainment system and little leg room.

What a silly survey to send - all AC flights were cancelled due to the strike so of course we did not fly yesterday
