The WiFi was down the whole flight, a flight that had no on board of any kind

Check in staff was incredibly rude and condescending. When I arrived at the gate I had been charged $125 for a checked back. I did have or check a bag. When I brought this to the attention of the staff member who checked me in, she said that she made a mistake and there was nothing she could do about it. I asked her to remove the charge and refund credit card, she said she could not and that I had to call my credit card company to contest the charge. I called Air Canada customer support, was put on hold, after 43 minutes a received a messages stating customer service was overwhelmed with calls and was then hung up on.

I wish to travel with Air Canada for my next trip

Refreshments and Air Hostess was good. Issues with customs in Toronto caused flight to depart and left me behind twice. Vouchers for delayed flight needs to increase.

They were very attentive, polite, professional and great customer service skills.

Bad experience. My checked bag was lost during this direct flight….how does that even happen?

Long wait to check in at the priority counter in Toronto

I had no communication, receipt etc from Air Canada until hours before flight

Customer service excellent. Food was poor. I received my luggage open with missing items.

They cancelled my return flight due to mechanical problems checked me on a flight a day late . Did not inform me kept sending me the old itinerary by email . I called and rebooked myself on an earlier flight still would not send me the right itinerary kept sending me the old itinerary The new airline charged me 150 $ for the first checked in luggage Aircanda was $75 . No effort to reconcile this or any apologies for anything . Sorry flight canceled… you are on your own Air Canada is worse than a budget airline Will never fly them again ..
