Airline reviews

They double booked seats, the gate staff changed my ticket as I was boarding she went over to the computer and changed it without telling me. She messed up an entire three row section for me and others. Other travelers were outraged but the gate staff were so rude, so condescending saying it wasn't their problem to solve. I would rate this a zero if I could. Will not fly Delta again I'll stick with United and American.

The flight was comfortable and uneventful, which is what I desire

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

None of the airplane features were available during the flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

I truly love flying with Delta. They have always treated me with the upmost respect

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight was great. The gate location was way to far away!!!

I believe that a four-hour trip should have a meal. Delta had none.

Much better than Spirit. I was please by the easy fast check in and boarding

Same thing as flight from Pheonix to Newark. Uograded and Promised extra leg room and when I got to the seat it had none.

Everything except the food and entertainment. It was a great experience though

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

Check how old the airframe is, some older ones have inoperable seat back entertainment or power.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Flight and crew were great. United didn't inform crew of immigration process which was disappointing!

One day, I do so hope for a gluten free snack! Seems like with the rest of the world FINALLY figuring out what gluten free is, American Airlines would too. Fingers crossed!!

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

Allow me to book extra bag check in as free though I packed in 1 luggage but that was 7 LBS overweight so make another bag to free check in.

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.

Refreshments and Air Hostess was good. Issues with customs in Toronto caused flight to depart and left me behind twice. Vouchers for delayed flight needs to increase.

Everything was good till we got to yyz...then we got to the gate and there was NO GATE AGENT. We waited 15 min before disembarking. No internet No IFE Old aircraft Second leg in two weeks NOT IMPRESSED

The seats are soooooooo small in economy. I was offered no tea or coffee in the am. When I asked was told that it was too late. The plane was 2 hours late leaving.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

Terrible - flight was flagged for fraudulent payment from being booked via Kayak. Requested to rebook with original credit card or provide new payment. Air Canada stay at JFK did not know how to process new payment. Had to fly from La Guardia 2 1/2 hours later instead with Air Canada.

Very poor.!!! They cancelled our flight and rebooked us with very little time to catch the flight. Our luggage was lost. As of now we do not have it yet. No clothes to change on the second day of vacation.

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

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