Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

The flight was actually good the staff was all friendly, but I have to give it a bad rating because my luggage was damaged and I was not able to claim that it was damaged. I only realized it once I got to my hotel and when I tried to contact Air Canada it was almost impossible. The number give to make claims is only for US & Canada yet I was in Seoul, when I tried contacting the number for Seoul I was once again told to call the other number or to return to the airport (which was not possible at the moment). So very disappointed that there was no way to claim my damaged bag and now I have to try to get a new bag while on vacation.

Mess up with not assigning my husband a seat when our two tickets were purchased at the same time. They put us on standby. We were almost bumped off the plane at the gate before departure. Luckily someone volunteered to get a later flight.

The flight itself was ok the staff was great and so was the inflight food. The biggest problem was that my luggage was damaged (the zipper pull from both sides of the zipper where completely ripped out) and I didn’t notice at the airport but at the hotel and when I tried to make a claim it was not possible for me because I have to either call (which is difficult because I’m in another country) I tried to call every nombre given to me but the one that I need I was never able to contact and going back to the airport was not an option. So it’s basically impossible to make a claim if you are abroad. Very disappointed that there are no other ways to claim a damaged bag and now I need to buy a new luggage while on my trip.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

it was our first flight with Air Canada. The flight was very good. The arrived 10 minutes early. The crew was attentive and very professional. The seats were comfortable and the food was fine. There were a lot of movies and TV shows to choose from. The boading was OK, but it is more about the Montreal airport procedures, but not about Air Canada.

Crew was very respectful and ready to serve. Much better than before.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.
