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.

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

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

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.

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.

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

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.

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

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.

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

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.

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

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

First My Flight was Delayed for Over 3HRS, I missed My Older Sister's Funeral, My Car Rentals I Missed it, Had to take Uber from the Airport and then to Rentals Next Day

As usual with Air Canada, being on schedule would be nice. Tv kept shutting off and having to reset it by staff every time. Irritating.

Air Canada was great and boarding was fine. The issue was that we received an email from Air Canada to check in (we were directed to Air Canada’s website). When we tried to check in online we couldn’t. So we decided to go to Air Canada check-in desks at the airport. When we arrived there they said that we needed to check in with United Airlines (which was in a different terminal and required an air train or long walk to get there). There was no indication during the booking process that we needed to check in with United so it was impossible to know. Hopefully this can be fixed going forward to travelers know which airline is processing their check-in. Seems like a basic thing that should be communicated during the check-in process. Other than that, everything else went well.

Both flights were good however , zero entertainment on YYZ to RSW flight. Helps to have some distraction on flights over 2 hours.

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
