Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

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.

While I appreciated the food (it was unexpected), it was interruptive for sleeping. We paid extra for reserved seats, but when we checked in they gave us different seats. I had to call WestJet arounf 11:30pm the night before our flight to get this fixed. We were give seats in the emengency row to resolve the issue.

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

I like the leg room in the exit isle..easier to get past people and I did t have to pay extra! Westjet changed my return flight time to a night flight 2 weeks before I left and left me hanging with NO HELP to resolve all the frustration they caused since I booked thru BudgetAir. They receive the lowest of star ratings I can give (if there was negative stars I’d be using those) for customer support and an overall bad score for the rest of the experience! So sad cause they used to good :)

Better boarding process, but not the fault of the airline… people are dumb.

It was a swoop flight at a west jetfare… the plane was literally a swoop branded plane.. I pay extra to NOT fly the budget carriers like swoop and flair so needless to say I was annoyed when both my outgoing and return flight were on swoop planes.

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.

Both flights we boarded and had to wait 1 hr/45 m respectively before leaving the gate. This was over and above normal times. Seats and space not comfortable.

Mutiple delays and changes of gate resulting in arrival 5 hours after intended.

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.

It was great other than the plane was really small

The crew members were great. The flight was awesome. But I had trouble getting to any of the movies. I tried over and over. The free wifi though is a bonus which I appreciated. Re comfort I am not telling you anything you don’t know. There is nothing comfortable about air travel any longer. As someone with a back issue I am usually squirming about two hours into any flight. But safety matters most of all to me and I do feel safe with air Canada.

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!

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.
