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.

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.

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.

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!

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10 Tips for people flying porter from Boston. The airline doesn’t have inflight entertainment No TV No WIFI. Bring your entertainment with you.

Wasn’t on the flight- again. Bad weather in Halifax and I was in an accident. What a poor experience to have to pay for all this flight and not be on it

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

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.

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

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

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

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
