The usb ports to charge phones laptops did not work.

Staff never asked passengers to bring their seat backs forward during landing. Was hoping to get a little relief from the passenger in front of me (I have long legs that I cannot stow in the overhead). Otherwise the flight was very pleasant.

Exorbitantly overpriced ticket. Flight was delayed as per usual with air Canada and there was zero refund or compensation.

Because you didn't have the tarmac clear and then had to unboard a plane I missed my connecting flight to CLE. Cost me a day ... a 30 dollar hotel hamburger ... then the next day THAT flight was an hour late to arrive ...

Delayed as usual with Air Canada. Checked the status of the fly online it said took off when the plain was still at the gate.

Delayed on the way in 2 hours!!! And now on the way home delayed then cancelled!!!!!

Delay in luggage again for the second time of the trip. I would not advise using air Canada or at least I will never check in a luggage. Luggage issue overshadows the nice crew members unfortunately.

Comfortable seats with good leg room. But not screens on seat backs.

On board wifi or other entertainment. Landlines option was good but ran late to Pearson

Flight was fine and on time. But no entertainment system and little leg room.
