Flight was smooth and comfortable. The crew were exceptional. Amanda, Nichole and Hershel were attentive to our every need. So friendly. My daughter and I were surprised at quality of service. Loved the double row seating. Snacks were delicious. We would definitely fly with Porter again. Flight PD 670 SFO to YYZ Thank you so much for the best flight experience we have had

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

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 delayed 6 hr. Looking for compensation and will claim for it.allow US people to fix to avoid huge delay having a canadian tech to fix it.

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

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.

New jet. Lots of leg room. On time departure. Early arrival. Reasonable airfare. Excellent online experience.

I had checked in online the day before but was instructed to collect our boarding passes when we arrived. I am not completely comfortable using the automated Kiosks and always enjoy the nostalgia of speaking with someone when checking in for a flight. Upon doing so however, we were immediately asked,"did you check in online already?" To which I replied, "yes, but we were asked to retrieve our boarding passes upon arrival." She then said, "that's what those machines over there are for. We really encourage people to use those." That unfortunately sparked a series of shortness and overall poor behavior in my opinion from the woman who checked us in. I understand it was early in the morning but I am always excited to experience flying and that interaction has unfortunately left a bitter taste in my mouth to the point I will forever now hesitate to book with Porter again. Thank you for taking the time to read this. Cheers, JD

Everything was fantastic, by far the best airline experience in Canada 🇨🇦!

All of our flights got delayed. Fll-Montreal delayed due to technical issues. We got transferred to a Fll-Toronto flight, in Toronto flight got delayed 5 hours causing us to miss our connection to Amman. We are now arriving to Amman 24hours later

In flight wifi that I paid for was very slow and at times didn't work at all.

Flight delayed two and a half hours from Toronto to Calgary Philadelphia to Toronto we were listed as standbys !!! Very concerning

Flight delayed at the last moment Hill next day and havé to drag at Hotel at our cost and bec day was again delayed 4 Times because no crée and no pilot

Flight schedule could be better. Leave Montreal early in the morning and return from LAX later in the day

AC announced early departure, but departure was delayed about 1 hour due to engine problems.

I like the tv show the seat was ok and the crew was awesome

Made me check my carry on and then lost it,

Tout était bien, comme pour la plupart des compagnies aériennes, le seul bémol était leurs système de divertissement qui a cessé de fonctionner en plein milieu du vol. Un peu décevant surtout quand il reste encore 2h de vol.

No free food service for a 6 hour flight! Paying for headset …… couldn’t even get a coffee
