First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

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

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

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.

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

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

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.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

Food offerings need to be more plentiful and beverages need to be more healthy.

First My Flight was Delayed for Over 3HRS, I missed My Older Sister's Funeral, My Car Rentals I Missed it, Had to take Uber from the Airport and then to Rentals Next Day

Nothing at all ! Everything was fantastic from start to finish 👏

Air Canada was great and boarding was fine. The issue was that we received an email from Air Canada to check in (we were directed to Air Canada’s website). When we tried to check in online we couldn’t. So we decided to go to Air Canada check-in desks at the airport. When we arrived there they said that we needed to check in with United Airlines (which was in a different terminal and required an air train or long walk to get there). There was no indication during the booking process that we needed to check in with United so it was impossible to know. Hopefully this can be fixed going forward to travelers know which airline is processing their check-in. Seems like a basic thing that should be communicated during the check-in process. Other than that, everything else went well.
