It was a good flight and we arrived on time, plane was clean.

The flight was fine. Long wait at security and for wheelchair. Got to gate about 5 minutes before boarding

Disappointing flight experience! ✈️ A two-hour delay, insufficient food and drinks, terrible cabin crew, and poor service overall. No toothbrushes or toothpaste provided for a long-haul flight — absolutely unacceptable! Compared with Japan Airlines, the difference in service quality is unbelievable. Overall, this experience was simply not good enough.

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Very good, easy to check in, 24 hours to cancel, good prices, nice flight attendants!

Great flights. Only criticism is when landed I. Montreal, wheelchair service has no signage or anyone letting you know where to go , just an older gentleman at the desk looking confused

This is a regional jet. As far as those go it was average. Again poor quality for an expensive seat. Not worth the upgrade

All went really well. Except that I was randomly chosen to be thoroughly checked!!

We were reluctant to travel with Air Canada after reading many bad reviews; however, we were more than satisfied with the experience flying from San Francisco to Montreal and back. Seats were comfortable (although on the return flight we had very little leg room) and the crew was friendly and competent. The entertainment was outstanding, with hundreds of choices, from movies to shows to comedy. Our luggage was delivered in a timely manner (a little slow in San Francisco) and we were sent tracking notices all along the way through the Air Canada app. I wouldn't hesitate to travel with Air Canada again.
