The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

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….

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

By modern air travel standards, our 15-hour flight to Delhi was very nice. Quiet-ish, straightforward, good service, okay seats, etc. All good.

Again, it was delayed and then our connecting aircraft was very cold.

It was very cold in the beginning; then I asked stewardess to do something about that, and she did something, so for the rest of the flight the temperature was closer to normal. It is typical: by some reason the pilots or whoever is in charge make the cod in the cabin unbearable. The seat is better than on WestJet or Flair, but is is very tight. No leg room.

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.
