We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

Terrible 3-4-3 seat configuration, I thankfully was able to choose a seat at the back where it narrowed to 2-4-2 for some relief though seats were still narrow. Staff did not manage the boarding lines at all either, was total chaos.

Seriously need to improve the time schedule and the plans

Great TV, easy boarding, wonderful ground crew and flight crew.

It was late leaving but made up time in the air.

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Squeeze like sardines. ANA has much better leg room. The food on air canada was disgusting. Worse that left over microwave dinner. Like you heated up microwave dinner then saved it overnight, then microwaved it again and added nasty garnish to try to elevate but instead made it as edible as cat food.

Crew was terrific. In flight entertainment system is very slow and the touch screen can be not sensitive enough or too sensitive. It was such a pain to pause a movie in case when I unpaused it accidentally thought I presses stop. This happened 3 times. I gave up and went back to my phone for entertainment.

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

Inexperienced crew. Food was so so. They lost my luggage on a direct flight. Was flying business so my luggage was priority. Not impressed.

boarding needs to be streamlined load the back of the plane first

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

During the flight there was a medical emergency. We were diverted. Of course I'm thankful they cared for the health of that passenger, but they did a poor job of communicating with the rest of us passengers. In the end we arrived at our destination several hours late, with no direction of how to rebook missed connecting flights. It all worked out in the end. Those of us that needed accommodations were put up in a hotel by Lufthansa until we could make it to our final destination. But it was United Airlines Personnel who really helped us navigate the process.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

Good boarding experience, staff was very friendly. No entertainment was provided and vegan/veg food items did not taste good.

The flight was cancelled, and no reason was given. The flight was rebooked 3 days later. Calling customer service was next to impossible. There was no option to get in a queue in the phone call. It simply said all agents are busy call back later. It is 2024 and not 1970s to have such outdated technology. Live chat was even worse as I was 753 in line and it kept getting timed out. The icing on the cake was that the working hours was something like 9:00 AM to 6:00 PM? Really for international airline when the flights usually depart early in the morning? Things only got worse in the check-in counter in Mumbai. The monitor in the check-in counter said that the flight was on time even though it was cancelled. There were 2 agents helping a 747 full of passengers. It was 5:30 AM by the time I checked into the hotel. I tried reaching Kayak (Chatdeal via email) days before the onward flight from Seattle and no one cared to respond even after reminder. I will go with Expedia in the future. In fact, for my next trip to Japan I have already used Expedia.

My 4 bags have been lost at transfer and I still have not received them
