Air Canada is not only the worst airline in the business but the worst business in history.

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

Delayed 3 hours. Gave us a food voucher for CA$15, to places that were already closed or not serving food. New plane did not have entertainment options. When disembarking, they had closed the direct route to baggage claim, rerouting us through another terminal 0.5miles away. Overall, a terrible experience.

Minimal food offered (crackers). Had to clean the seat with a wet wipe because of dried food.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

I overpaid for the trip. They would not consider giving me any compensation or a credit.

ground crew at Casablanca as well as at Montreal was not helpful at all. specially at Montreal airport, very rude .

The speakers were way too loud. Music was played during boarding too. This noise could've been avoided.

Service was excellent, but they ran out of food options by the time they got to my seat (row 36).

The idea of needing to go outside in the winter to board in icy cold temperatures is totally a non starter for me. Seats were very uncomfortable though the leg room not too terrible. Attendants were nice
