A very comfortable flight, an additional wash room could have made it almost perfect.

A very comfortable flight, an additional wash room could have made it almost perfect.

Look, I understand that Kayak doesn't know I cancelled my flight on Porter. So I didn't actually fly yesterday. My main disappointment is with Porter ticket fare policies, and maybe you can pass this on to them: At my employer's request, I had booked a full fare ticket with no change fees since my trip to Toronto would likely be extended. Indeed, when I went to change my flight home to a later date, I was told the Fare Difference would cost an additional $550. So much for no change fees lol! While I had the agent on the line, I hopped over to Kayak, searched for new flights on the date in question, and saw a one-way ticket that got me home for only $355. So I got reimbursed about $450for the unused half of my roundtrip and bought a new ticket for $355. What good is a full fare / no change fee ticket if they screw you with "fare difference" BS. I'm still flying home on Porter Airlines but they just lost a hundred bucks with their stupid shenanigans.

I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.

It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

Organization and the adjusted times but the snacks could be of a bigger portion

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Due to mechanical problems it was delayed causing problems the actual flight. Was fune

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.

Nothing to like about porter. Flight cancelled. No flight back to Boston for 2 days. No hotel accommodation. Terrible. Never again by porter.

On one of the flights, the situation became sufficiently frustrating that a passenger openly expressed their dissatisfaction. Despite these complaints, we did not observe any meaningful improvement or receive an adequate explanation. The fact that members of our group experienced similar conditions on two separate aircraft is particularly concerning. We recognize that cabin temperatures may vary during a flight; however, the prolonged discomfort and the apparent lack of an effective response significantly affected our travel experience. Passengers reasonably expect a long-haul international flight to provide a tolerable cabin environment. When multiple passengers raise concerns about their comfort or well-being, those concerns should be acknowledged and addressed professionally.

Flight was really good, with no middle section on an A321neo for an international flight, from Ottawa directly to London. Staff was friendly. The food was okay, and entertainment amenities could be better.

The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The crew was great. There was no entertainment and the internet wasn't working. We sat in the run way for a LONG time which is always so upsetting. The seats are very close together and the flights are completely full which makes for a tough flight. Flying is just an uncomfortable experience.

Very kind crew. Vegetarian food better than usual. Prompt take off. Entertainment worked well. Could always do with more room!

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

It’s ok just the boarding point is far too far

My flight was cancelled and United Airlines could not rebook or help. My whole trip was then cancelled and I could not go to the funeral I needed to get to.

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

I paid for a comfort class seat and was seated in economy.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight was delayed but at least they let us know early about it (the night before)! Everything after that was smooth!

Air Canada was on schedule, fast, and took care of me the whole flight. With affordable price, I 100% recommend you fly Air Canada if you are able to.

Late, almost 3 hours late. I have whiplash from how many times our ETA was changed.

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

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….

Delayed. Change of gate . No hot beverages served. No snack.

This flight was better than the tokyo to toronto one

would be easier if earphone was provided or wifi was free . No point having entertainment when you can’t listen with wifi earswt

This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.

Air conditioning was out for about 15 minutes that made it uncomfortable. WiFi went out halfway into the flight. Flight was about 45 minutes late.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

Good service, friendly staff. Food was average for airlines and the seats were small.

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

Due to the long delays and rescheduling boarding was horrible. However, the gate staff and the flight attendants went above and beyond to remedy our frustrations. They were able to handle every potential harsh situation with Grace, compassion and coolness of head. Kudos to the MIA Gate A12 and night crew of flight 1572 YYZ to MIA.

I liked nothing about this particular flight. Not only it was initially delayed for two hours due to late arrival of the plane, but the flight attendants were also very late to show up coming from a hotel (based on the announcement made by the gate agent). They did not arrive on another late flight, so why couldn't they be on time? Total disrespect of the passengers!! The plane itself was cramped and the seats super uncomfortable. To top off the poor experience, my video screen did not work. To summarize: flight delayed for 3 hours, cramped and no entertainment (for me).

They kept posting delaying flight due to maintenance issues from incoming arrival flight since 10am, the flight is supposed to depart at 3:45pm, after kept delay until 12am, they finally said it’s canceled. What were they doing for the last 13 hours? After 2am, they still don’t find hotel where we can stay. terrible experience!

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints
