The flight departed more than an hour later than expected. The flight itself was good. No other problems.

It was pretty good. The transatlantic flights can be tough on any airline, but this was a decent experience. The only thing I disliked was the airline crew moved my carry on bag without telling me or explaining anything. If I was sleeping during that part, I would’ve assumed it was stolen.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.

Bad, we had 3h delay without clear understanding, which lead to missing my connection flight.

Liked that it wasnt a full flight but we were asked to check carry on luggage as we were told the flight was full so i did, and that was not true. There was tons of empty overhead bins. No entertainment, and only one drinks and snack service when my ladt flight on aircanada in February, Montréal to Victoria had 2 drink service offers in the 5 and a half hour flight. Why only one this time? It felt very "budget" and cheap

Connection was easy to find and quick. Plane was older but comfortable. The food contained beans again so a similar problem of being in a tin can in the sky after eating beans. Overall flight was uneventful which is great.

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Flying with Air Canada is not pleasant at all. The plane is very old, meaning that there is no on board entertainment, the leg room is less, and it is dirty and in poor repair. To make matters worse, the crew was pleasant enough on my initial fight, but very rude on the return flight. Furthermore, the website advertises many amenities for international flights that are not honored when you were flying from the US to Canada even if your flight is five hours long. Even if you are willing to purchase food, they will likely not have over half of the advertised options available. In addition, you will pay twice the amount of a child’s order for an adult order of same item even though it is the same size as the children’s. It was just really bad on many levels I will try to avoid flying with Air Canada again at all costs

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!
