The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The crew was great. There was no entertainment and the internet wasn't working. We sat in the run way for a LONG time which is always so upsetting. The seats are very close together and the flights are completely full which makes for a tough flight. Flying is just an uncomfortable experience.

Very kind crew. Vegetarian food better than usual. Prompt take off. Entertainment worked well. Could always do with more room!

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

It’s ok just the boarding point is far too far

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Flight delayed any hour and couple of big gate changes

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Flight attendants had a little attitude. Food tastes no good.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

Maybe glass of wine would be nice at no charge

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

Access to movies was rather confusing. Apart from that, I have no complaints.

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Flight left on time. The crew was very friendly. I had to buy a proper meal. Small cookie and a drink just doesn’t cut it for a 4.5 hours flight.

Experience was good, the wifi hook up is somewhat tough

No dogs! Can we have no dogs in the cabin? Why was there a yappy little dog behind me? Lucky I had ear plugs. Sorry for others without

Arrival at Comox from, London,ON 6 hours later... No bueano

Flight delayed, missed my pick-up had to Uber, plus missed dinner and medication, so sad!

I booked through westjet. The first flight left late and cost us the connection to the second flight. The second flight after a 4 hour delay was again late because they were short an attendant. Then a door malfunctioned on the plane which led to yet another plane. So by the time we left Calgary we missed the BC ferry and had to pay a charge to get a later one. It ended up being a 24 hour day. That wrecked our first day and part of the second day in BC because we were so overtired.

Delayed on the way in 2 hours!!! And now on the way home delayed then cancelled!!!!!

Delay in luggage again for the second time of the trip. I would not advise using air Canada or at least I will never check in a luggage. Luggage issue overshadows the nice crew members unfortunately.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

The baggage drop-off for Air Canada in Toronto for passengers flying international was terrible. One of the worst experiences I have ever had. The line was ridiculous; there was no one to help facilitate people avoid confusion, and the baggage system for the line I finally ended up in had to be re-booted right as I got to it.

Flight got canceled. Instead of the booking me for the next flight at night I was booked for the following day at a later time. I was able to fly out that night because I had to call and deal with a human!!!

My flight was delayed My connection was almost missed. My bag was lost My valuable items get damaged

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

It might have been closer to being on time. Maybe next time I could fly from London to Toronto?

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.

The experience was awful. I didn’t expect to pay $100 for my luggage both ways. Then we start boarding late, they then make us go back out of the line and go back into the airport for maintenance. The delay was 45 mins and I also hated the fact that I paid so much and still had to pay for a seat when I checked in. I will not be rebooking with this airline

Very bead I am going to Vancouver to toronto. Not boarding receive. Before flight ✈️ time I have to take boarding. Boarding manager asking me pay $89 . Just flight ✈️ time before I pay .after provided the Boarding pass. Flair Airlines management not good. But kayak is best application.

Leg room was terrible and seats very narrow. Flight was also delayed.

The crew of this flight, specially the flight attendant in the front were the sweetest I’ve had in all my life, I genuinely hope they get a race or sum cuz of their efforts. It was just quite unsettling that the flight took so long to departure. It was supposed to leave at 10:35pm and we ended up taking off at 11:22pm…👎🏻👎🏻👎🏻

It’s bare bones but was on time so can’t complain.

TThe first time I have ever flown with flare and both ways sucked

I try to buy water the cabin crews told me I had to wait for them to come around with the trolley I waited over 2 hours !!!!! Literally 2 hours I was so thirsty .

Lots of leg room in the front rows. Wish water was free.

The worst airlines I have seen in my life they don’t respect anyone they don’t care about anyone they lost our luggage and no one is responding. We waited for five hours to get our luggage back.🤬🤬🤬👎🏻👎🏻👎🏻👎🏻

Great staff. Cramped seating for someone 5 feet, 2 inches and average weight. So if you're tall or heavy -- good luck. Even if you wait until the 24 hour checkin time, you still charge for seating. Really? So either it is a less-than-pleasant experience or pay the price of a "big name" airline. And if I'm going to pay their prices, why would I fly in your cramped seat? So, in the end, you want to give less comfort for the same prices as Air Canada. Go figure.
