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 Flight took off 2hrs late because there was no pilot showing up when the flight was ready to board.. Though the cabin crew was present and had prepared the plane, the FO turned around after 15 min and went away. A crew to fly the plane finally arrived over an hour later and we were able to board 1h30 min later than planned time... until everything was loaded, we left 2h late from the gate. This was a small plane, so don't expect any Entertainment... Wi-Fi access on board would work, but took an awful amount of time to figure out and get it work (I'm an IT person). Flying as VIPorter customer, I was expecting at least some warm meal, but everything served was just cold.. except the coffee maybe. Even in so-called VIPorter seats, space is cramped and trays are so tiny, you can barely setup your food. Flight caught up during the coast-to-coast crossing and was able to recoup about 45 min from the delay.. still arrived very late in Vancouver and had to wait a long time to get our registered bags. Let's see how the return flight will be in a few days..

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.

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

All good the seats a little tight and no I pad screen

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

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

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

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.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Was the longest flight I have ever taken to Orlando. Not Westjet’s fault necessarily. There was a traffic issue in Orlando. We sat in the airplane for about 2 hrs before leaving Calgary on a 5 hour flight was just a little long to be stuck in the plane. Once we arrived in Orlando we were stuck in traffic on the ground for another 30min. I guess maybe the flight could be delayed so boarding would have been later so we wouldn’t have to have the discomfort of being on the plane so long.

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.

Seats were comfortable and leg room was good. Slight delay for boarding but nothing too bad. Would fly with them again.

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

It was awful. The communication between corporate and the crew on the ground left more to be desired. The crew even said that Corporate was waiting on answers because they themselves didn't know. Every hour, there was a new excuse. I also understood that passengers were angry, but the crew should have done a better job at crowd control. There was a racial exchange between passengers that could've been avoided has the crew acted sooner.

We sat on plane at gate delayed without communication as to why we were just sitting there

The flight was on time and crew were nice, seats were tight and there was entertainment available

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

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).

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Be careful about the bad policy and when purchasing seats

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

Horrible, experience, 5 hours delay, they changed gates 3 times, the last one we had to wait for 1::30 hre for the door to open to get to that gate. 0 apologies from Air Canada, they don’t care at all about their passengers

The plane was filthy!!!! There were empty food wrappers in the pockets and worst of all a wad of hair where someone had obviously brushed their hair, cleaned out the brush and left the wad of hair in the pocket. It was the most disgusting thing I’ve ever seen!! The seats are so crammed together with NO leg room. The AC vent controllers do not adjust. I will likely not book another AC flight from Florida to Montreal.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.
