Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

I’ve wasted 7 hours of my time because of the delayed. ;(

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

Overall great. The crews were lovely. The seats are awful. I always emerge with a back ache.

I liked the behaviour of the crew members.The flight was good.

The WiFi was down the whole flight, a flight that had no on board of any kind

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.
