Seriously need to improve the time schedule and the plans

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

It was late leaving but made up time in the air.

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Squeeze like sardines. ANA has much better leg room. The food on air canada was disgusting. Worse that left over microwave dinner. Like you heated up microwave dinner then saved it overnight, then microwaved it again and added nasty garnish to try to elevate but instead made it as edible as cat food.

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.
