A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!
Much roomer than air Canada! Great flight for the price. No complaints
As a first time flyer with Porter I was happy with the service and comfort of the airline.
Other than wifi no on board entertainment. Will use them again, roomier seats than other airlines and snacks and beverages, better than average
I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc
The flight was half empty yet they charged me $50 for a basic carry on! I saw how passengers of different colors were treated differently.
There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!
Three hours on the tarmac with almost zero communication from the cockpit. Not when offered a water in the interim. In my 67 years of flying all over the world the worst experience ever. The plane was half empty, however had to pay for seats to sit next to my girlfriend. Extra to take a carry on. I would never fly Porter again even for free.
Porter is what Westjet used to be. Staff were great
The upgraded seats on the smaller flights I guess is a toss up if you get a full meal. We paid less for the ticket on the way there and got a full meal where we got a snack and drink on the way home. The lounge was also in the other terminal too. No entertainment on the seat and no wifi on the plane.
It was a short flight so, everything went smoothly and we got to where we needed to be safely.
Flight home was delayed multiple times, did not get home until 2am
Super experience. Earlier than schedule departure and arrival. Baggage handling was very good
Check in agent was very helpful and polite. He helped me board the earlier flight back home instead of waiting 2 hours at the airport for the next flight
Our flight was canceled at the last minute. Someone on the flight said the exact same thing happened to her the day before. I will say they helped us book a flight on another airline so that we could still make our vacation with little delay.
The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!
Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.
The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.
Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.
