Airline reviews

The Carry-on luggage that approved by TSA and all other airlines,- always an issue with Air Canada. This is inappropriate as my carry on suitcase meets the requirements however it always asked to check in on AC flight on the gate. Yes I have it for free, but it takes extra time to pick up on the carousel. Apparently it fit the overhead space, so why AC has this issue all the time?

The Carry-on luggage that approved by TSA and all other airlines,- always an issue with Air Canada.

Yes I have it for free, but it takes extra time to pick up on the carousel. Apparently it fit the overhead space, so why AC has this issue all the time?

Too many notifications. Non of which were useful. 4 hours before traveling we discovered that we needed a transit visa. That's useful information. Air Canada should flag and keep flagging that up. Then the useless too much information had us go to Paris not Brussels. Chaos involving the customer. We will try never to use AC again.

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.

My flight was canceled and next one was 1 hour later. The gate was changed 3 times.

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.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

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.

I did not get to this flight because of the reason I mentioned in previous review

Hated every minute of it. Delayed for over 10 hours only to have to cancel rental car, car insurance and hotel. Its taken me 3days to get to my final destination when it should have only taken 12-14 hours. Very unhappy with Lufthansa.

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

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 Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

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