There was No Flight. Both Kayak and Porter refused to honor my booking. I was asked for an additional 1,300 $ CAD to keep the flight. After several emails to both Kayak and Porter I was ignored. I had to cancel my March spring break plans, dog kennel and hotel. I had to re-book another vacation to Nassau in January w Expedia. I had to re-book a new vacation for spring break. Porter and Kayak both blamed each other and would not work together to fix this. Not cool.

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

The flight was a little delayed but check in was easy and boarding was quick. Luggage was quickly available and everything worked great.

The Flight took off 2hrs late because there was no pilot showing up when the flight was ready to board.. Though the cabin crew was present and had prepared the plane, the FO turned around after 15 min and went away. A crew to fly the plane finally arrived over an hour later and we were able to board 1h30 min later than planned time... until everything was loaded, we left 2h late from the gate. This was a small plane, so don't expect any Entertainment... Wi-Fi access on board would work, but took an awful amount of time to figure out and get it work (I'm an IT person). Flying as VIPorter customer, I was expecting at least some warm meal, but everything served was just cold.. except the coffee maybe. Even in so-called VIPorter seats, space is cramped and trays are so tiny, you can barely setup your food. Flight caught up during the coast-to-coast crossing and was able to recoup about 45 min from the delay.. still arrived very late in Vancouver and had to wait a long time to get our registered bags. Let's see how the return flight will be in a few days..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

Due to a known technical error that Porter has not fixed in over a year, I was unable to check in the children on my reservation online and had to do it at the airport. Upon check in, there were no seats together, which was an issue as we had young children. The gate agent did manage to seat us together by moving other passengers, which was appreciated, but the other passengers were never informed, leading to confusion and delay upon boarding. The flight was over an hour late; no explanation or apology was ever issued. The bags on Porter take a long time to arrive--over half an hour at Hamilton on my inbound flight, and not much better on my return to Edmonton.

Much roomer than air Canada! Great flight for the price. No complaints

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

As a first time flyer with Porter I was happy with the service and comfort of the airline.

3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

We are a senior couple (70+) and chose emergency exit seats so we would have 2 seats together and neither of us had to sit in a middle seat. My husband is type 1 diabetic on an insulin pump and I monitor his blood sugar levels. I am 5'9" and 250 lbs and found the seats extremely uncomfortable. Toward the end of the flight I developed diarrhea which lasted a full 24 hours.

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

I was very nice to arrive earlier than scheduled. Very much appreciated. No issues with flight. All was good.

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

We were treated well by the staff at the airport and on board aircraft. Delay was uncontrollable due to the weather. Had to wait for another gate as we were late landing in Fort Lauderdale.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

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.

The Turkish was good . I had a problem with air Transat terrible experience for me

I thought the coffee was excellent! The wait for the luggage was acceptable.. It left and arrived on time. My son found that his device worked very well and he really enjoyed his flight! The stewardess moved him up to the emergency exit and he very much appreciated that!

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

The flight was cancelled less than 24 hours before departure. The alternate flight was a day later going from Grenada to Toronto to Vancouver to Calgary to Montreal. 2 days in the air. Not serious, Very bad service

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

Liked in-flight wifi Did not like - nothing to complain, really. All good

The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

Smooth flight Staff were courteous and welcoming upon entering and exiting the plane Pilot and crew provided frequent updates Leg space was not pleasant but manageable

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

Flight itself good .Landing at terminal3 and connections to terminal1,it is connections nightmare,specially for disable person

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

Crowded and tight fit on Rouge. Entertainment requires your own mobile device. Small bag of pretzels is only food for 3.5 hour flight.

Other than flights being cancelled and 3.5 hours late causing missed connections it was ok.

The plane was almost an hour delayed and then once we were on board, they said that captain didn’t have enough hours left in his day to fly us so they had to find another captain. Surely that could’ve been figured out out in advance. Incredibly frustrating because I missed my connection in Toronto, and it has a result missed the first day of my conference in Charlotte, North Carolina.

Flight from saskatoon to toronto was by far the worst flight ive ever been on and roughest landing ever.

Mechanical issue caused me to be stuck in Vancouver for 2 days

The on-board entertainment system was horrible - we gave up watching because it just kept glitching.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

I wish Air Canada would provide a meal on the 5 hrs or more time flight to the passengers.

Terrible… Luggage’s missing for 5-days. Not expedited despite notifying them that insulin and ozempic were in bags and required refrigeration. I’m extremely disappointed. Meds were useless upon delivery as ice pack had dissolved and meds were warm and not useable because their efficacy and potency are now questionable . I’m so disappointed and expecting a full refund for the checked in bags.

flair is a scam. They give the impression that they’re so cost effective with wonderful service. To cut a long story short. You end up paying so much for every little thing (even water) it all adds up to much more than some of their competitors. I’ve tried with Flair for several trips, but I’m done with them now. There’s no real benefit anymore. I would rather pay a little more and get a service that I’m comfortable with. Goodbye to Flair from me.

Their "free personal" requirement is to have your bag fit in a containment frame that is way too narrow and slender than the space under the actual plane seat (the length of my vitamin water was longer than the width of the containment frame. They had personel at the gate literally designated to hounding people's bags in the zone line up, and forcing them to measure their bag again if he felt "the bag might be too big for personal item". If your bag was too big for their scamming measurement criteria you had to fork up $110 CAD for the carry on cost ($85 at the 24hr online pre-check in). Plane had no entertainment, seats did not recline, and no complimentary snacks or drinks. Unless I have a short flight with zero bags, I won't be flying Flair ever again.

Flight attendant said bye bud. Lol peak flair right there

On time flight. Reasonably comfortable seats. Disliked having to pay for refreshment and snacks.

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.

Not good Even after I made my booking, I was charged $90 for my boarding pass. I have collected boarding pass i pay $90 near . Flair airline not good. Without pay no boarding pass.

The flight was smooth, but the seats are not comfortable. I was not able to sleep. The sizes for the personal item and carry-on are way smaller than other airlines.

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

The worst airline experience that I ever had in my life. The fare was cheap but boy do you pay for it when it comes to baggages, carry-ons, food on board and lack of available staff at check-in. Almost every other passenger on my flight had the same complaints and experience. We all bonded discussing our displeasure. My husband and I will definitely not be traveling with Flair Airlines. We'll take anyone else.

The most uncomfortable plane I ever fly on. The seats won't even recline a little. For a 5 hrs flight at night and tired it felt like torture
