Mutiple delays and changes of gate resulting in arrival 5 hours after intended.

It was great other than the plane was really small

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.

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!

Crew were friendly and efficient. Love the hot towel service!

No possibility to get a refund or rebooking because of illness.

My flight cancelled 3 time and rebooked. It was unexpected for me. Otherwise everything is perfect.

I supposed to have a wheel chair waiting to take me to the luggage carousel. Didn’t happen so I had to walk up the walkway with my cane. I lost my balance and broke my little toe on my right foot, which means that I’m hobbling around with a very painful left leg and a very painful toe on my right foot. It was a nightmare.

It was a very pleasant trip from A to Z.

Every leg of my trip with Air Canada was delayed Never offered as much as a small bag of pretzels on. 3 hour trip Printing boarding passes at the airport when told to bring printed boarding passes with you Unable to load passes into my apple wallet- so very easy with other airlines
