food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

The staff on the WestJet flight were friendly and helpful. The flight was smooth and we arrived 30 minutes ahead of time.

not as spartan as an air Canada flight, less comfortable / no in-flight screen as compared to similar priced Air Transat flight. Crew Cabin were professional and approachable. They got the job done, safe flight, on time despite delay in take off.

There was no entertainment and no announcement till well after I and others asked about it, and no "compensation" (like a free snack)

4 hour delay, lost our bags, staff was loud and it was an overnight flight

Entertainment was the only issue. I did not have app & not equipped to watch movie on my phone. Used to other carriers with access to a screen for viewing. Other than that, everything was fine.

Great flight. Pilot was able to fully make up the 42 minute late arrival of the aircraft for an on time arrival in Toronto.

Westjet delayed then rebooked us on flights for economy class when we paid for business class and now need a refund for fare difference and they aren't getting back to us

Our plane entertainment system was out… That made for a very long flight. In my opinion, WestJet should consider a credit or a partial refund for that.

I liked when we actually were allowed to get on the airplane back to Edmonton… What could’ve been better well, not having our flight be delayed five hours could’ve been better… And then canceling our flight from Edmonton to Toronto, and then rescheduling us to fly from Honolulu to Edmonton -Edmonton to Vancouver, and then Vancouver to Toronto with a 12 hour layover in Edmonton pretty much was hell… Total travel time to get home 38 hours that’s really what could’ve been better. The two gate attendants for WestJet in Honolulu told us to come back to the gate to try to make other arrangements because they had to board the Calgary flight 1st and they didn’t have time to talk to me but by the time I came back when they told us to they said you should’ve come earlier to make these arrangements everyone else already changed their flights… We found out later that 30 people did not get on the 2:30 AM Edmonton flight. They ended up getting on the midnight flight to Calgary and making other arrangements to Toronto and so forth which we could’ve taken advantage of that if they had allowed us to when I initially had went up and approached the two gate attendance one of their names was Denise. One of the kindest WestJet employee was the one who received us in Edmonton, who felt so bad about the entire situation she got us for more meal vouchers and flew us first class from Vancouver to Toronto. In Honolulu they had given us two vouchers to use for dinner and they weren’t valid outside of Canada so we had purchased a meal and they were completely useless… But nowhere did it say that they could only be used in Canada So when we received more food vouchers in Edmonton, all of them did end up working in Canada, but it was just so convoluted. Overall, we have traveled to other countries even going as far as Africa… and that experience was far easier than flying to Hawaii from Canada I cannot believe any of this happened and how inconvenient it was We arrived, exhausted after 38 hours of travel, and could not even go to work on Monday. I look forward to hearing from KAYAK or from WestJet for some sort of compensation over the situation.

The Air Canadian personnel were all very professional and friendly. I will definitely fly on them again.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Not full, so lots of room, which is really the only thing that can make flying economy more comfortable. Direct to Toronto is great! I didn't eat or use the entertainment.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Not much food available, not able to choose seats to be near each other, tv did not work

Flight was good and staff was efficient and friendly. Being a discount airline, they charge for carry on, food and beverages. I did not partake, but your survey doesn't have a n/a button. My only thing was that it felt like I was sitting on a cement block. My behind was sore after a couple of hours. I was not able to check in on line, so very thankful that the linecat the airport moved quickly. I think I will use Swoop in future if I just need to get somewhere and don't need to bring carry on bags.

Bring your own water, do not expect and comfort on the plan, and over priced gross processed food. Drinks were could (paid for) and saw we needed to bring our own water for a 5 hour flight. Kinda shitty you have to pay for carry on- same price and stowaway luggage. The luggage cost more than 2 round trips from Toronto to Victoria bc. Shocked at that

Airline did Not inform us is further delays to an already cancelled flight. Big chaos prior to boarding.

I would take swoop for a 1, maybe 2 hour flight MAX. Every thing is an up charge, even water. The seats don’t recline so it makes it very tough sitting in that small space. The crew was amazing though, they went above and beyond to try and make the experience comfortable. Also, we were delayed a total of 4 times - 5 hours.

I've flown with swoop a few times and always had a good experience. The crew are pleasant and helpful. Thanks

It’s a no frills airline, professional and gets the job done well.

Nothing at all. The flight attendants couldn’t care less about the passengers. Overheard 2 complaint about being “too tired to bother or care about anything”. Complaining about working 2 jobs and was even too tired to care about returning a lost pair of glasses that they just threw away. Never flying this crappy airline again.

Really nice flight barring a one hour delay, which was already informed. Staff at abbottsford check in counter was very friendly and helpful. Her name was Robin.

Lack of staff Airplane (even with upgraded seats) was not comfortable Boarding took extremely long, no system in place Inconsistent messaging on reason for delay

I sat near a man who continually took his mask off. He was told to put it on 3 different times. He would say “ oh sorry” then remove it as soon as they walked away. By the end of the flight they had given up and they all walked by him “maskless” and didn’t say anything. He coughed and sneezed throughout the flight

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

Of all the countries I've flown to and airlines from around the world, I have never had such a dismissive an arrogant employee during boarding. After waiting in line for 20 minutes to board, I was sent to a second line for Passport verification. Natalie from Flair, repeatedly tried to scan my passport which didn't work for some reason but was too lazy to input my information manually. Bar code scanners aren't 100% reliable as we all know. She asked me my birthdate 3 times, made me wait to be the last person aboard and then smugly threatened me that my only bag could be charged for (same backpack I used as on my arrival as carry on). Natalie working in Ft. Lauderdale and the was the epitome of lobotomized tiktok brain with the charm of junk mail.

Food selection is very poor and sears are very uncomfortable.

Flight was 3 hrs late and another 2 hrs wait for baggage to arrive on carousel and a $7.00 food voucher that arrived as we were boarding our flight.

Seat rows so close together no one dares to put their seats back. Knees pressed against the seat in front, had to find a position putting my legs under the seat in front. But for 6 hours keeping that one position was ridiculous. All savings on the purchase price are taken back through charge backs for luggage $200 each way, Seat selection $44 per seat or you are seated by a computer randomly. Wife sat 5 rows away. Would avoid Flair in the future

The flight was safe (priority). Everything else is low-cost: too hard, delays, mediocre boarding, cost for carry-on and checked luggage.

Flair flight was 4 hours late due to not having a crew and the plane was filthy. Just water service Terrible experience flight 1513

Flair did not notify you when they changed gate number!

Can't be happy with a 5 hour delay. Only given $10 voucher for food and still EVERYTHING was an upcharge during the flight.

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