The flight was fine see earlier note for the problem

Three hours on the tarmac with almost zero communication from the cockpit. Not when offered a water in the interim. In my 67 years of flying all over the world the worst experience ever. The plane was half empty, however had to pay for seats to sit next to my girlfriend. Extra to take a carry on. I would never fly Porter again even for free.

All good the seats a little tight and no I pad screen

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

Flight was delayed over 2 hours, then landed at a different airport!

The whole experience from check in to deboarding was fantastic.

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

In spite of purchasing premium, I felt it was perhaps the most uncomfortable seat I have flown in. The base was either broken or poorly made and had no support. Even placing pillows and blankets on the seat (1D aisle) didn’t help. It made for a long and mostly sleepless six hour flight. Crew also were very loudly talking to each other through the night making it very hard to sleep. It was purchased for the price, so I get the risk, but was not impressed.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

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

Generally good. However. The flight left 30 mins behind schedule with no reason given.

Great breakfast and coffee …..fastest bag service I have ever had in NOLA

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Orlando to Canada, despite being close and an international flight, the plane was not at all comfortable. It felt like the chair was being pushed forward, in addition to not having a TV and having to choose from a tiny glass of drink, for example, water or soda. I couldn't have both. When I asked the flight attendant for an extra glass of water, she looked at me with an ugly face. This is ridiculous. They don't want to give water to passengers. I will never fly with this airline again in my life.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

This was an excellent experience for a very short flight.

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

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

Seats in 1 res are dispersed all over the plane, even child was across

Personally, I will not use this fight again. The service is poor, you have to buy even water. They don't provide anything even sneak, you have to buy. They said Personally items for 7 kg. Then they use some measurements, if you have 7kg and if it's not getting inside of their measurements, you have to pay 80$ this is robbery. I will prefer other flight then this. I am désappointement taking this airplane.

It’s a shameful company. It ask as to go to counter to take the boarding pass, they simply send it by email, just to check the bags’ size in a smaller than normal template. DONT USE FLAIR! It will be more expensive than normal airlines at the end.

flight was okay, no wifi, no free drinks but worst of all they lost my son's bike for four days. Customer service was nonexistent - call a number that leaves you on perpetual hold, there's no baggage folks in the baggage claims area (in vancouver). we went up to international and nobody was at ticketing, went to domestic and they had us fill out a form. they could not tell us where the bag was. Anyway, highly recommend you drop an airtag for anything that's worth more than $500. My son's bike costs a lot more than that to replace; I was on pins and needles for four days.
