Better than usual. We’ve flown air Canada for years at least once or twice a year and used it to bring our Canadian American son back and forth from USA and Canada and Europe and we have had MANY bad experiences with late flights, missed connections, boarding issues, for almost 10 years. Just lots of bad experiences. This one wasn’t bad at all. It’s simply what we expected. Even though the first flight this time was 45 min late in leaving due to a maintenance issue, that didn’t mess us up. But all else was fine so we were pleased.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

All good, but plane outdated, seat uncomfortable, food that we had was 4 out of 10. Crew was great!

Lack of crew staffs to handle emergency medical situations that ending no meal served and only hot water and bag of pretzels served for business class!

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved

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

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

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

Multiple change of the gates at Pearson, delayed flight was extremely uncomfortable.
