Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

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!

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Staff was friendly helpful also good timing I rate it a 10 out of 10
