The flight had to return due to maintenance issues and then was cancelled

The space for seats were uncomfortable and lack of leg room . I paid extra for more leg room. I’m not a big person.

In flight entertainment system did not work across the whole plane for entire flight. Seats were very cramped. Cabin temperature was freezing cold. Crew was miserable and answered everyone in a short and barking manner. I’ve flown air Canada many many times and never had an issue. But this was unpleasant.

They screwed up so bad, I asked for a short check for my luggage since we had a 21 hour overnight layover in London at a hotel. They said I have to receive my luggage in London because it’s an overnight layover. Get to London, nope, my bags aren’t coming off they are staying in terminal 5 over night and going straight to Ibiza. So we had no luggage for a whole day and basically stuck with no clothes or washroom stuff. Finally get to Ibiza and my luggage is completely smashed and damaged and missing a wheel. Now I have to drag this 50 lbs luggage around Ibiza islands for 10 days. Wtf. So pissed off Air Canada is LITERALLY THE WORST AIRLINE IN THE WORLD

Great flight ✈️ I requested a vegan meal and don’t think offering frozen fruit cup for breakfast is a good idea people want something warm or neutral like the muffin but it was cold from being in the paper bag with the frozen fruit 🧐 and unfortunately I didn’t have either and I don’t like wasting food so that was a disappointment. Flight was on time departure and arrival flight crew were good.

Food, service and the boarding/offloading aspects were great. Our only issue were the seats we booked in the exit row because it was next to the bathroom so we were interrupted all night by people waiting for and then opening and closing the door to use the facilities. Would have fine for a day flight but not so much for an overnighter.

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.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

After nearly nine years without traveling, my son and I decided to take our first flight, and we chose Air Canada and I’m so glad we did! From start to finish, our experience was nothing short of amazing. The flight itself was smooth, comfortable, and truly enjoyable. The staff were warm, professional, and went above and beyond to make us feel at ease. But what really stood out for me was the luggage tracking feature. Knowing that my bag was scanned onto the same flight I was on gave me such peace of mind. It’s little details like this that make all the difference, especially after not traveling for so long. This trip was incredibly special for us, and Air Canada made it even more memorable. Thank you for such a fantastic experience I wouldn’t hesitate to fly with you again!
