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.

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.

Westjet forced me to put my carry-on baggage in check-in probably because I was assigned seat 23A (the last row seat), which had no cabin space, which is unfair. I wanted to carry on my luggage so that I don't have to wait at the airport for my luggage. Also, because there was no cabin space, I was forced to keep my laptop bag under the seat, which I didn't want to as I was carrying 2 laptops and charger. The airline should basically tell people that if you are assigned a last row seat, then you are not allowed a cabin baggage or a personal item.

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

Easy processing, flight time was quick and staff was professional and kind.

It was delayed by two ours very full no room to move

They seem to have squeezed out a little more legroom in these planes! It was very nice to not have to fold in half to fit in the seats!

Flight late …60 minutes No food No wifi No entertainment system A disaster!!!

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.

The flight I was connecting with waited for me even though my 1st flight was late. I really appreciated that.

The seat is too hard and my back and bottom are having servers pain

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

Great crew, friendly. Found the trip long just sitting with no onboard entertainment

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

I didn’t like the fact that all the customs officers went to lunch so I was in line for 90 minutes due to where the staff directed me. We were told three very different reasons for why the plane was delayed. It was a crowded plane with difficult storage situations for the Carry On bags. The Air Canada airline staff were all very good and professional. I was so disappointed in my cheese and fruit box as the cheese had molded and the fruit wasn’t fresh so I couldn’t eat the majority of the food. This was the last meal I could find as the restaurants had closed when I got in to my destination. I think you could work on improving the food quality.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

The staff were so kind and helpful. We flew back from NY with another airline and it was horrible. We will always stick with Air Canada as everything was far better!

The boarding process in Toronto bad as they share space with domestic flights and when those domestic flights come in you are locked out behind closed doors until they are done and then its a mad rush to get your boarding gates and board. This is not so much due to Air Canada but with the GTAA, but Air Canada could use different gates especially early morning in order to prevent such travel angst.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

Not happy with Air Canada . Flight was cancelled got the run around trying to get another flight that was direct none to be found ended up going to Denver then onto Austin adding 7 hours to our trip. Was travelling with some one who had walking issues that’s why we were happy to have a direct flight then it didn’t happen adding more stress on her

Well you cancelled our direct flight to Austin from Toronto granted you got us on another flight but sent us to Denver then onto Austin delaying our arrival time in Austin by 7 hrs I was flying with 3 other people none of us were happy with our Air Canada experience

I wish there had been more seat options...when I tried to book, there were only.middle seats available. Do travel agents get first pick??

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.

TThe first time I have ever flown with flare and both ways sucked

There was no entertainment There was no food or beverage service , not even a glass of water The plane door could not be opened upon arrival
