Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

The TV screen at my seat was not functioning for the entire duration of the flight. I informed a flight attendant about the issue, and I was told that I would receive a voucher as compensation. However, I never received this voucher afterward. I therefore kindly request to still receive the voucher that was promised to me.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

As mentioned before the fact that my paid-for aisle seats had been changed to non-aisle seats is unacceptable. Happily one staff member at the boarding counter did correct it before the flights, otherwise I would have been forced to submit a formal complaint. If it happens again on return flights, I will put in a formal complaint.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Everything could be better, the worst is the crew, looks like they are not happy in the work. Air Canada is downhill for years, every flight looks worst. Hope they can fix the issues, by now, just flying AC in toutes with no other alternatives. Shame.
