Nothing special. Unacceptable wait for baggage on arriving in Calgary

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!

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

No real issues just wasnt able to hear / understand any announcements flight attendant was making but everything else was really good- ended up checking my carry on case for free which made deboarding quicker. I would fly West Jet for all my flights.

Seat comfort could be much better but it was economy so......

The staff and crew at all points were warm and professional. The Westjet app was a plus.

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.

New jet. Lots of leg room. On time departure. Early arrival. Reasonable airfare. Excellent online experience.

I had checked in online the day before but was instructed to collect our boarding passes when we arrived. I am not completely comfortable using the automated Kiosks and always enjoy the nostalgia of speaking with someone when checking in for a flight. Upon doing so however, we were immediately asked,"did you check in online already?" To which I replied, "yes, but we were asked to retrieve our boarding passes upon arrival." She then said, "that's what those machines over there are for. We really encourage people to use those." That unfortunately sparked a series of shortness and overall poor behavior in my opinion from the woman who checked us in. I understand it was early in the morning but I am always excited to experience flying and that interaction has unfortunately left a bitter taste in my mouth to the point I will forever now hesitate to book with Porter again. Thank you for taking the time to read this. Cheers, JD

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

All went fine. Boarding was efficient, staff was really friendly, and we were kept up to date on any changes to our itinerary. My only note for improvement is that on this particular plane, the recline in economy class was negligible. I know it's a coach seat, but I had another UA flight (SFO to BWI) and the seat was more comfortable with better recline.

Really good experience with a redeye flight from SFO to BWI. Boarding was efficient, plane was comfortable and newer than others, lots of audio and video choices, and staff was great. I appreciate United's service.

Was a good flight. On time. Was full and all went well

My flight from Toronto was delayed but the connecting United flight waited for me 👍

The original seat on the flight Toronto Newark had the floor flooded with coffee spilled, so they changed our seat to premium economy. For the flight from Newark to San Salvador we were i the last row, no reclinable seats and beside the toilet. I asked for headsets to the waitress and she gave it to.me test of all the passengers, while she was staying right behind me..

Couldn’t get the tv screen to work, didn’t try food, so no comment

Flight was delayed but reasonable notice and communication was always there for the passengers.

As is pretty much the norm with Air Canada now, we left late from the gate (45 minutes late). This is my 12th flight with AC in the last 12 months and 10 of those flights were either late or cancelled. AC essentially has a monopoly in Canada so they have carte blanche to charge exorbitant rates now and give poor service, with no repercussions.

A 2 hour delay because they couldn’t fit some oversized cargo in the small hold doors of an Embraer! Surely they know the sizes before attempting to load it?

-kayak did not give me advanced notice to my e-mail for my flight and I had major trouble finding the code to access Air Canada’s site because you did not provide it to me and incompetent Air Canada did not have any access based on my name alone. WTF -The flight was delayed twice. -They moved the boarding area -They said I would give free checked baggage because the plane was full and they charged me over $30 -They didn’t get my luggage on to the plane and left without it and I’m heading to a cruise ship. -I have lost one FULL day of my limited holiday and had to cancel scheduled events because my luggage did not get on the plane (even though the plane was delayed). -The “wheresmyluggage.com site is a total incompetent disaster that caused additional stress. -I will be sharing this experience

Plane was a Rouge vacation flyer for some reason. No legroom and entertainment. People were desperately looking for USB ports and such. And then there is this notorious and unsolved space problem where not all carry-on fits in the cabin….

They did not have any meal options left on the menu. Only snacks.

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.

Horrible that they pack so many children onto a 10h flight.

The crowding at the gate to get on is ridiculous.

Check in was great! Boarding was very good. The plane was just okay! The crew were great!

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

I try to buy water the cabin crews told me I had to wait for them to come around with the trolley I waited over 2 hours !!!!! Literally 2 hours I was so thirsty .
