Airline reviews

Flight was delayed for over an hour making our connecting flight impossible to make. No notification that we had been bumped to another flight. Was told my bag would stay at the airport. Got to my hotel and got notified I needed to pick it up. Come all the way back to the airport to find I didn’t need to pick it up and the app glitched. They did at least put me on the next available flight. No offer for money back or compensation for time lost due to being home a day later. No compensation for food as it was only good for anything in the airport. Not outside it. They did at least book the hotel and the gate agent was very helpful. But I did not appreciate them giving my seats away to stand by people while I was sprinting through the airport to try and make it to a flight I was late for through no fault of my own. If they did not let stand by on I would have been on my flight as they did allow two people before me on

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

Comfortable seats with good leg room. But not screens on seat backs.

I was rescheduled when I missed my flight due to border clearance issue

Air Canada has very professional , friendly and co operative crew.

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

I liked that the staff members at the airport were helpful and very pleasant to work with. Flight crew were also a great crew who were helpful and I was happy for their help boarding. Overall a pleasant trip home.
