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 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.

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

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

It was perfect! I've never flown with United before, but I definitely will in the future

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

Overall all good with the flight. Appreciated the extra spacious upper storage for (vertically standing) carry on. Efficient crew, on time departure... What could it be better is the in seat power. No one was working in our row. We were counting on the in seat power to recharge our battery depleted phones. With the dependency we have in our mobile devices nowadays, the availability of in seat power is a must....

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

Experience was good, the wifi hook up is somewhat tough

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

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

I had a problem checking in as I didn’t have the correct code. I had to phone BudgetAir.com. They charged me an additional 174US for some tax or something in order to provide me with my booking number. I will never use a third party seller again. Absolutely criminal activity. But I did get to where I wanted to go

Never been on a long haul flight that didn't have on flight entertainment. I hope the way back is better !

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

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

Long delay die to pet mix up. Also bags took forever to get to carousel

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😍👍.

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline

I have flown on many airlines all over the world, and this plane flight was the most uncomfortable I have ever experienced.

It was delayed then we turned around so not good.

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

Left two hours late, now screens and WiFi wasn’t working. Unacceptable on a 6h gate to gate flight

Original flight was canceled due to bad weather...not a problem, completely understand however I had booked a direct return, instead I was rebooked with a layover of over 2.5 hours. What should have been just over 2 hours turned into 6 hours. Snacks on-board were pitiful and they were constantly out of beverage products.

Not even a snack on a five- hour international flight? Really? One drink serving? Really?

The cabin crew was fine, nothing out of the ordinary. However, the crew at check in was a disaster. We had already checked in and wanted to see if we could upgrade to first class. Waited in line bc the crew was so slow. No sense of urgency. Long story short, the lady, Maria, would refuse to answer our questions directly. As we are about to leave, she asked if we wanted our boarding passes printed. I figured we were there, already wasted time, might as well. We could have gone to through security as we were already checked in. As she’s putting in our information, my bf has to step away, leaving me with out two carry on. I just had surgery and was in a sling as I don’t have much strength or movement in my left arm. She looks down at our carry ons and said we need to make sure it fits. I told her, I haven’t had an issue with it as this is what I flew with from the states to Canada. We both flew with the same carry ons. She just said to me, it doesn’t matter. I also asked her if this is a different procedure with this Air Canada as I have flown to multiple countries and states with this same carry on. She said the same policy apply, which at this point doesn’t seem true since I have gone through multiple cities and countries and multiple airlines with zero issues. I struggled to go over to the stand and once again, struggled to lift my carry on into the rack to see if it fits. All the while, she just stands and watches. Her and the manager both standing there and watching as I dropped and struggle to lift the carry on. My carry on was too wide due to the wheels and they refuse to let me use it. Then, to make matters worst, my bfs carry on, which was clearly smaller than mine, she then asked me to do the same thing, lift it to see that it fits within their measurements. Of course that one fits. But, again, I’m disabled and both the agent and manager stood there, not once offered any help. She forced me to check in my bag with the fee. I should have just walked away because, when we got to the gate, the crew there also asked that anything bigger than the slot gets checked in, FOR FREE. Maria took advantage of my disability, was unsympathetic and just a disappointment to Air Canada. And the manger, that was more interested in making other people’s lives miserable because he was clearly miserable should quit trying to flirt with Maria and actually do his job. What a joke of a staff and what a joke of an air line.
