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..

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

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.

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

travelling in 14th of April and now we are in 17th , I have not received my lost/delayed bag... this is very bad and the worst part is their call center is not able to see where is it!!!!

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

Hard to criticize after the Crowd Strike dilemma. However, when Air Canada says they were "not affected," I expect that is true. My flight delays caused me to miss transportation connections. I understand these things happen, but I don't have to "like it."

Not good. Flight delay. No entertainment. No screen. No food. Warm water to drink. Early in flight. Awful dirty bathrooms. More flight delays!

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

New Airbus 220 with all the amenities. Not sure why hot beverages were not served as flight turned out to be very smooth…

We were delayed over six hours. It was horrible. They kept delaying the flight further every 15 minutes the whole time so we were kept in limbo.

When my plane landed in Toronto, deplaning was delayed due to terminal security issue. I had a somewhat tight connection flight to St. Vincent, and no one from Air Canada ground crew made any effort to notify my connection flight gate of the issue although I plead with several ground crew members to notify desk at departing gate.

At boarding I can’t make out what the intercom is saying at boarding.

They did a fine job. I bid on the auction and won a business class seat. Service and food were fine.
