Airline reviews

We were not able to board the flight to Halifax. Westjet switched to a smaller plane and we were booked on a later flight which was not acceptable to us. We were told that they attempted to contact us but did not have contact information. Nor did either Kayak not Kiwi advise us. In February I booked a flight to Sri Lanka through Kayak with FlightHub for myself and a friend. We were advised of a change in schedule and because I was travelling outside of Canada at that time, my friend, Louise Lore, contacted FlightHub and revised our itinerary. Our original flight from Toronto through Frankfurt to Mumbai was to arrive in time for us to catch an 8:45pm flight to Colombo, Sri Lanka on February 28th but because of the change did not arrive until 1:00am February 29th. When I arrived in Mumbai I was told that my flight from Mumbai to Colombo had not been revised and that, because I was a no-show for my flight all of my tickets had been cancelled. Ms Lore spent from 2:30am until 5:30am on the phone with FlightHub trying to rectify the situation. She was told there was nothing they could do and a supervisor refused to speak with her. The next morning I went to the Lufthansa office at the Mumbai airport and the problem was resolved in less than 15 minutes. I will not be booking through Kayak again. Both experiences have been disastrous and I cannot imagine going through this again Linda Toole

The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day. Her inch long fingernails said it all....I really don't belong here. Other than that, WestJet personnel provided a good travel experience, especially in flight. I must say that the repeated announcements about the cabin being full and how folks should gate check their bags became tedious. WestJet should just offer free checked luggage and charge for carry on suitcases. It would save a lot of time and the voices of the gate agents.

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Departure delay on a late night flight. Made us even later. Tired but got home.

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

My experience was just great ,no issues at all, I will definitely fly with you again.

Horrible. I accidentally added the name Charlie instead of my given name Charles and was denied boarding with no recourse to fix it and no refund.

Seats and leg room were tight but then all airline flights are like that unless you pay extra juice. Flying is no longer to be enjoyed ... only endured. Sad.

Fine. The plane took off and landed. Food was as expected. Less than comfortable flight.

I couldn’t upgrade into a different ticket class and was unaware I was booking basic economy. Baggage was an extra $125 and seat selection another $150. Cramped seating and terrible food. Plus no coffee in the morning.

I could not check in on my AC app. You have a glitch in the system for multi dual passports. When entering Canada from NY I have to use my CDN passport. When I go back home from TO to USA I I have to use my US passport. Your check in system for my return flight would not let me enter my US passport and was not flexible. Demanded a resident number or another alien number That could not change to my US passport number. This did not happen before. Annoying had to check in with an agent. Please fix

First lag from Toronto to Vancouver. Cold as hell and there is no blanket to provide. Terrible crew and bad attitude

Experienced flight cancelations and delays in 5 days. They seem pretty common to AC. Experienced with one of AC's check-in agents at the counter of a big liar. She lied and acted (yes like acting in a movie) that an early flight was fully booked and refused to rebook me, but my flight was delayed two hours so I could not make my connection. Later, I got help at the gate to switch the early flight (Big thanks to that agent). Ater boading, I found the early flight was only 2/3 full meaning there was almost one vacant seat in a 3-person seater, and multiple empty 3-seaters. AC is wired that it is filled with good and bad employees. BTW, AC employees seem never smile, or they don't know how.

Flight was delayed at least 4 times then once we boarded they found a problem with the plane and we had to de-plane and wait another hour for a different plane. I was an hour late for my performance.

Not much food/snacks. I had just tea and it was so bitter.

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

The crew of this flight, specially the flight attendant in the front were the sweetest I’ve had in all my life, I genuinely hope they get a race or sum cuz of their efforts. It was just quite unsettling that the flight took so long to departure. It was supposed to leave at 10:35pm and we ended up taking off at 11:22pm…👎🏻👎🏻👎🏻

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.
