Staff was not frankly. I asked about what beverages you have and air hostess told me like before so very rude answer.

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.

I liked that the plane landed safely. I didn't like that the food and leg room is horrible.

Liked getting into Milan at 10 AM. Also ok to get into LAX at 9:35 pm. - less traffic driving home. Layover a bit long - say 3-4 hours each way. Montreal airport kind of grim these days. Would lose the duty free area. Think art versus advertising. Maybe local shops and food spots. And keep layover short - like 1 hour on Finnair in Helsinki.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

Everything could have been better from the planes not being delayed to the rudeness of staff to it was just horrible will not use kayak again or Air Canada I can't see what would ever change my mind now

I wish someone would wake me up so I could eat the free food :( slept for 90mins on a 10hr flight and I missed breakfast. I’m sad about that lol.

Business class was not worth the extra charge. Overpriced for slightly larger seat. Nothing special. Small older plane.

Both flights are delayed so I rate the whole experience as mediocre.

Bad experience flying with air Canada . Seats not comfortable . Checked bag was delayed and was bought home next day by airport employee. Had to buy toiletries since bag was delayed . No compensation was even suggested . Will not fly air canada again
