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

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.

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

4 hour delay, lost our bags, staff was loud and it was an overnight flight

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.

Entertainment was the only issue. I did not have app & not equipped to watch movie on my phone. Used to other carriers with access to a screen for viewing. Other than that, everything was fine.

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.

Westjet delayed then rebooked us on flights for economy class when we paid for business class and now need a refund for fare difference and they aren't getting back to us

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

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Not full, so lots of room, which is really the only thing that can make flying economy more comfortable. Direct to Toronto is great! I didn't eat or use the entertainment.

Not much food available, not able to choose seats to be near each other, tv did not work

It was a domestic flight so the food was not included. But we had not even a little snack and by the end of the flight they were coming around serving water.

Got the email to check in but when I tried to check in it said "cannot connect to server", so checked in at the desk.

For me was not enough water. + 200 ml would be perfect… Generally it was good.

Lovely staff for a short flight! Complimentary wine too made me happy.

The flight is very short, may be a little snack can be offered

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

The Airbus ride was noticeably different in a positive sense. Beats the 737 in leg room, which is important for my height.

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.

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