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

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.

I didn’t receive any help when they messed up and wasn’t honest and the supervisor did absolutely nothing to help me so I had to buy another ticket at $537

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.

Due to a known technical error that Porter has not fixed in over a year, I was unable to check in the children on my reservation online and had to do it at the airport. Upon check in, there were no seats together, which was an issue as we had young children. The gate agent did manage to seat us together by moving other passengers, which was appreciated, but the other passengers were never informed, leading to confusion and delay upon boarding. The flight was over an hour late; no explanation or apology was ever issued. The bags on Porter take a long time to arrive--over half an hour at Hamilton on my inbound flight, and not much better on my return to Edmonton.

3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.

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

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍
