Average flight, comfort was as expected for a 10 hour flight. The service was fine.

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

Food was not inspired but was satisfying. Same for infotainment selection. You’d think business class would come with complimentary WiFi. Crew was uniformly attentive and excellent.

Better movie options. More diligence on the size and amount of bags people bring on board. Lady across aisle from me had a bucket style bag that would only go so far under the seat in front of her. She was not told once that the whole bag is supposed to be under the seat. Crew is very hardworking however.

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

Flight didn’t happen because both my connections were lost and Toronto wouldn’t let me board. I was checked in to all 3 flights at the check-in fest in Dublin.

Flight was delayed for 5hours. Food vouchers just aren’t good enough

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

Business class lie down seats on WestJet aren't very comfortable. Crew were excellent and overall flight was ok.

A group of a family sat behind me. I think up to 8 people? Constantly talking and making noises. Stewardess did nothing at all to make them stop. Told the Stewardess and they said they'll handle it but they didn't 🙄. Food sucked too.

It was great to have a vegetarian meal option, but departure was delayed because they had oversold the flight. Air Canada, you’re in charge of how many tickets are sold: don’t oversell!

I liked the quiet airport and no queue. I don't like that when booking it is not clear that there is teared economy, that you have to pay extra for choosing a seat and for your luggage both ways. We didn't find this out until checking in. It turned out not very economical.

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.

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!

Overall the new aircraft’s is good and crew is good. Just overall airline policies and process needs to be better.

Mostly crew good and the flight was safe and comfortable but service was lacking. For an overnight flight of 8hrs 50 it took some two hours to get served a drink and dinner after take off. I asked for Laurent Perrier champagne and was brought Perrier water, which I queried and asked where was the champagne. No response. The issue came up again an hour later when dinner was starting to be served and I was asked whether I wanted another drink, when I reminded I was still waiting for my first champagne! Apologies ensued but dinner service was quite slow. For breakfast I never did get served the hot course! So - no complaints and compliments on the safety of the flight but service underwhelming (and I brought them candies!)
