My flight was canceled and next one was 1 hour later. The gate was changed 3 times.

They changed my flight twice. The 2nd time they changed it they did so the day before the scheduled departure and replaced the lie flat seat in a 777 to a 737. I paid extra to be in the 777 only for them to change it. Then the departure was delayed twice. The connecting flight was also delayed.

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

The last minute change of planes, then putting us right beside the bathroom was a poor choice.

Terrible 3-4-3 seat configuration, I thankfully was able to choose a seat at the back where it narrowed to 2-4-2 for some relief though seats were still narrow. Staff did not manage the boarding lines at all either, was total chaos.

Seriously need to improve the time schedule and the plans

We were delayed by rain while we were on the tarmac. The crew came around and offered everyone water while we waiting 45 min in the plane.

Great TV, easy boarding, wonderful ground crew and flight crew.

Air Canada cancelled my prepaid/prebooked seat selection and changed my seats without any options.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth
