Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

Overall great. The crews were lovely. The seats are awful. I always emerge with a back ache.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

I had boarding pass on my phone. Husband and I were seated together. Agent printed out boarding passes and we were separated for the flight

You was on strike and I had to get another r flight and you did not give me my money back

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

Really out of Air Canada's control due to long delay because of mechanical issues. While doing their best, disappointed by their assumption that all passengers have smart phones. Should have communicated food voucher availability at gate area. Late arrival cost me an extra $51 because public transit was not available, Otherwise, feel Air Canada did their best dealing with their challenges. Will likely continue using them in the future.

Air Canada decided to go on strike less then 24 hours before our travel and we had to cancel finding flights elsewhere.

This was the end of our honeymoon and our connecting flight to Philly was canceled while we were in our layover due to “maintenance”. Filing a claim to get compensation but would not fly Air Canada again.

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.
