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.

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.

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

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

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.

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.

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.

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

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

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Flight delayed any hour and couple of big gate changes

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
