Delays after delays only to announce we don't know how long it will take

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Very tight seats - no legroom at all, very tight to the person in front of you. If you have basic fare, you are loading zone 6 regardless of where you are sitting in the plane - meaning even as a middle aisle person at the front of the plane, I had to get people to get up and let me in as they had boarded earlier. Having to pay for a carry on is criminal. I am a frequent flyer, and air Canada has now joined the list of other terrible North American Airlines.

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….

I travelled in Business class for the first time and wish I could do that again.

the seats aren't the most comfy -- too little padding and I could feel whatever the passenger behind me was doing. Otherwise, it's all good.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.
