The airplane has been replaced and late night layover have been extended from 3 to 7 and the only compensation was a $15 food voucher after most restaurants have been closed, not helping with children after a 18+ hour international flight

The airplane has been replaced and late night layover have been extended from 3 to 7 and the only compensation was a $15 food voucher after most restaurants have been closed, not helping with children after a 18+ hour international flight

Just a two hour flight... boarding was smooth and easy going... flight was smooth... crew very helpful... snack of pretzels was awful, that needs changed...

It was good. The tray on the seat was not cleaned from the previous flight. The seats are tight but I had no one beside me. The crew was great.

The flight was great. I like it when airline capitalism give you information. For someone with flight jitters it really helps. And this captain was very cheery and reassuring. I had trouble understanding the head flight attendant because she spoke very fast. But overall staff were very helpful and kind.

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.

They went on strike before time and screwed us big time. Which is not fair. We respect their planned strike but why they went on strike ahead of time ??? Poor garbage management

Awful. As we were boarding we were told the flight was cancelled. Then had to stand in a queue for 3 hours to talk to someone at the kiosk of Air Canada. They were not helpful at all. No empathy. My issue is not with them striking but the total disregard for the chaos and distress late notice caused. No thought on the impact this has caused.

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.
