It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Limited snack options cause the snack vendor was on strike

The 6 hour delay with minimal updates was not handled well. After many complaints from most of the un-boarded passengers, food vouchers were offered. The catering strike meant there was no food or snacks on the plane. Beverage service was heavily impacted, only water or juice was available. The staff at the gate was kind enough to inform that "if you want to eat on the plane, you will need to bring it on when boarding".

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

I go am isle seat because it was half empty Food strike no food available

Flight was delayed, jeopardizing the following connections. Food was terrible. Crew was great.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

Great experience on this Air Canada flight. Everyone was polite and respectful, even the passengers are very polite.

My wife and I especially liked the fact that the Toronto agent went beyond expectation to allow my wife and I to sit together. There was no option for us when we booked our seats. Very thankful!
