Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore

Air Canada continues to disappoint in almost every way. Probably the result of a monopoly, so NO need to improve anything
