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.

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.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Very smooth flights Toronto to Rome and return. Crews were great, food was fine but very narrow seats and limited leg room. Aisle seats on our return helped with a bit more space.

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

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

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

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

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

I liked the behaviour of the crew members.The flight was good.

Food can be better. Taste and option, the pasta wasn't the greatest.

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

Flight was fine and on time. But no entertainment system and little leg room.

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

No food to provide, they forgot that, in some cases, people stay at the airport for hours without food. Now, to provide them with food, they have to ask them to pay, because some don't have money. That way, they can't eat.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

It was good to receive a card for my birthday

Horrible flight cancelled had to buy another very expensive ticket

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.
