Airline reviews

After waiting in the airport from 7am (to make sure we had enough time for security), our flight was continually delayed until it was canceled. They tried to book us on a Delta flight, which we considered and even went to the Delta terminal with our luggage (which was stowed and then available once the flight was canceled (about 15 min away) but were then informed that we would need to retrieve our luggage at LaGuardia and then recheck in to Air Canada in New York, grab our luggage, and then get to the air canada terminal and re-check in. We decided against it, took our luggage into an uber home and then drive the 6.5 hours (one way) to Montreal instead.

Flight departed significantly late with no announcements being made. Woman behind me would not allow me to recline my seat so I was unable to comfortably sleep. Flight attendant not very responsive. Slow to pick up garbage after meal. Not a good experience at all. I felt like cattle rather than like a valued customer

Hoping for small compasation for having to rebook my trip back cause i had to miss 6 hrs work

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

I like the fact air Canada is on time The food you guys serve is not good

Flight was great. Meal was really good. Boarding was terrible. Too many people in a small boarding lounge, zones not clearly marked.

Flight was delayed 3 times. My luggage was sent to Saskatoon instead of Casablanca - airline got it sorted out in two days. Received $45 in meal vouchers to use in the airport.

The crew members were great. The flight was awesome. But I had trouble getting to any of the movies. I tried over and over. The free wifi though is a bonus which I appreciated. Re comfort I am not telling you anything you don’t know. There is nothing comfortable about air travel any longer. As someone with a back issue I am usually squirming about two hours into any flight. But safety matters most of all to me and I do feel safe with air Canada.

Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.
