On-time boarding, departure, and flight. Electronic notifications about bags for the whole of their own journey too - from when they got accepted into the system through to being loaded onto the plane and then finally being disgorged onto the right carousel. That was an excellent feature.

On-time boarding, departure, and flight. Electronic notifications about bags for the whole of their own journey too - from when they got accepted into the system through to being loaded onto the plane and then finally being disgorged onto the right carousel. That was an excellent feature.

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

Aircanada was not great. Didn't get anything to eat. No snacks. No entertainment. Horrible checking in.

It was 3 hours late and ruined my plans at destination. Also rough landing.

I had a great experience at YUL Air Canada. The service was top drawer as I needed help to board.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Almost no food given on a 5-hour flight (only a cookie, which is almost a joke). Boarding was a mess (as always, in Montreal boarding by zones is chaotic and the lines are a total mess). The entertainment system was old and with a limited selection.

Very nice comfortable spacy Airbus 321. I liked the offer of food on the Bistro menu. The idea is very good to pay and cost was low.

Very bad I put my stuff down to go through the machine and when it came out it my watch was gone. Then they have the nerve to say I have to file a report that's b.s.
