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.

Seats not as comfortable but understand as it was a smaller plane/ short flight. All in all, I’ve never had any issues with Porter. Great company to fly with

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.

The staff was amazing. Best service I’ve had on an aircraft in a long time. Was not particularly happy with the food. Flight was at 10:50 and left home too early for breakfast and wasn’t able to purchase food at airport and felt for sure I could get some breakfast to buy on airplane. Nope as food was served around 11:30 and only one choice left (I was at 22C) so ordered the chicken dish thinking I’m getting a hot meal but cold chicken with rice and carrots etc. I was looking forward to a croissant sandwich and a hot cup of tea. The FA was kind to explain they were serving dinner at that time. She was lovely Other than the disappointment with the food the staff was amazing. On my return flight I will make sure to eat and take some food with me so I’m not hungry or disappointed. This was my second time ever flying Porter and will consider checking them when I next come to visit my daughter. Have to say it again best crew I’ve ever experienced on a flight and I travel quite a bit. Thanks.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

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

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.

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.

Porter, like most airlines, need to improve their baggage policies. In reality, there are no longer 'cheap flights' because passengers pay exorbitant baggage fees.

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

I think I'd sum up my experiences on this flight (Edinburgh to Toronto) by saying that Boeing 737s are simply too small for long-haul, transatlantic flights. The crew were excellent, the food was pretty good and the in-flight Wifi was a bonus. But 7+ hours on a narrow bodied aircraft with a single aisle and no in-built entertainment system, is a tough stretch - queues for the few toilets on board were lengthy at times; plus whilst the crew were doing food/drink service the aisle is blocked. It encourages you to stay in your seat the entire time (not great for those who need to get up and move around regularly) and the legroom is tight anyway. If this was priced as uber-budget, you could perhaps argue that you're getting what you paid for......but it wasn't and the price we paid was pretty standard for such trips (around £500 pp). I'd therefore urge caution and check the aircraft that is being used if booking with Westjet for flights to Canada from smaller regional airports on the Western edge of Europe. They do operate Boeing 787s from London and other major European centres - but it seems that if travelling from Scotland/Ireland the 737 is the aircraft of choice.......

Maybe glass of wine would be nice at no charge

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

Access to movies was rather confusing. Apart from that, I have no complaints.

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Flight left on time. The crew was very friendly. I had to buy a proper meal. Small cookie and a drink just doesn’t cut it for a 4.5 hours flight.

Experience was good, the wifi hook up is somewhat tough

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Flight was re-scheduled for the next day. No voucher for a hotel offered. Boarding was delayed by almost 1 hour. No free meal or even water was offered on board. When tried to purchase a coke, was denied because they didn’t accept coins less than 1 euro denominations. A young male flight attendant was especially rude and unhelpful.

Not a tonne of food for purchase items for early morning.

My flight got Delayed due to the airline. The attending Crewe in Montreal were not super helpful and I arrived 13 1/2 hours late from my original arrival time. Air Canada lost my luggage, they stated they booked me a hotel room overnight at no fee, however when I arrive to the hotel, there was no reservation. It also took me three different attempts to get the hotel, even covered by Air Canada as they were arguing that they were not responsible for this, despite it having been delayed due to the airline. Overall, the service was very very poor and what should’ve been a short five hour trip turned into a 13 1/2 hour saga with me, spending a night in a random airport overnight due to Air Canada’s errors, and searching for my luggage until 2 o’clock in the morning. I will never fly Air Canada again.

Not great. Missed my connection flight, due to AC issue. We were sitting on the tarmac for 90 mins before taking off.

Flight was delayed and rescheduled 3 times before being cancelled. Flight was also delayed on our flight in at Moncton airport on August 10th. Never flying with PAL again.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

It was out first time flying Air Canada and it was ok, comfort-wise. I hope airlines are able to get a quiet room installed for young children flying. Screaming and crying the whole time in business class is quite unfortunate. That was the only thing that really messed up the experience.

Staff were very friendly. Plane left on time and arrived on time.

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

The crew was amazing! I was a bit surprised and disappointed that there was not wifi available for personal use. The only thing I would change would be the seat cushions. They are not comfortable at all for long flights.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

In business on the top-deck of an overnight transatlantic flight. A family with uncontrolled young children were there too. All night they were running around up and down the walkway while squealing . . .

Boarding was weird. They boarded two flights at the same gate at the same time. So mass confusion for the non English/French speakers. So many people at such a small gate. Like every other part of this airport you have to walk miles between everything. Gate to plane was a 5 min walk :) several long flights so I was worried about my steps but ended up walking several miles here so worked out.

The service and food was excellent. The remote control for entertainment did not function properly.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

Everything was fine except that the ground personnel in Toronto wasn't able to operate the jet bridge, so that everybody was stuck in the plane after landing for 40 min, so I missed my connection.
