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.

Flight was delayed over 2 hours, then landed at a different airport!

Amazing and light experience, boarding on time, crew is super nice, clean salon and special thanks for movies availability. Provided by United Airlines

It would be nice to have access to the headphones since wifi wasn’t available. Passengers in front of me got them for free I was asked to pay for them. I heard stewardessa saying that headphones are complimentary since there is no wifi. When I requested headphones I had to pay. No room to sit. Bear given with the can but my drink was given in plastik cup. I will try not to fly with air Canada any more.

Boarded on time and arrived early. Overall quick flight. Snack and beverage offered.

Fine and uneventful I got to my destination safely No inflight entertainment Seats are not very comfortable

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.

Unfortunately, my experience was disappointing. The crew were not friendly or welcoming, which made the flight less pleasant. Our flight was delayed, and we almost missed our connecting flight because of it. To make matters worse, the gate number shown on the digital ticket was incorrect, causing unnecessary confusion and stress before departure. Overall, the lack of accurate information and poor customer service made this a frustrating travel experience.

Food was great, I wished there was better options for movies.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

AC Gate area in Toronto for small planes is not good at all
