This was my second leg of my trip and was delayed so was worried about my connection in Montreal. Still hungry so on boarding I asked a flight attendant if I could use my $14.00 voucher on the plane for food as I was starving. She said she would check and let me know but she never came back. So no food again as none was offered. Had to get my bags and check them again and that was ok but don’t understand why I had to go through security and because of them almost missed my flight. No food offered nor possibility to purchase food so still hungry and just watched a movie and hoped I could get food when I landed. Was able to use the $14.00 voucher to buy something and had my family bring food as I was now starving. I’ve been travelling on AC for years and this was my worst experience ever. After our flight got cancelled in SXM and was told the staff there didn’t work for AC so couldn’t do much to help us was not a good experience

Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

My original flight was cancelled and then rebooked four hours later on a recovery flight, but I was checked in as stanby and had no seats so as a family of four we were concerned about not being seated altogether. Our flight then got delayed by another 1.5 hours and when seats were assigned at the gate, three of the four of us were together and we could get my wife closer, they offered no assistance.

Good boarding but extremely cold temperature in both flights (60 F!).

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

Crowded and tight fit on Rouge. Entertainment requires your own mobile device. Small bag of pretzels is only food for 3.5 hour flight.

Other than flights being cancelled and 3.5 hours late causing missed connections it was ok.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.
