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.

Great! Personable crew. I love that they pour complimentary beer and wine.

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

I like the web site, prompt notifications, website checks in process, and airport check in. The flight attendants are attentive and polite. The return flight was 2 hours late and reason vine doesn't sound like an unplanned and unexpected issue (scheduled plane maintenance).

Not only was the flight delayed more than 3 hours but also there was no internet or movies on the flight. It was Flair/Spirit quality of experience at Westjet prices

The flight was delayed repeatedly, on the day of and in the days and weeks beforehand. The staff are alway fantastic.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Horrible, flight on the way to Vegas was delayed significantly and then on my way back my second flight was cancelled

Our flight experience was great! Flight staff was funny and offered great service. Made record flying time coming home from Vegas after having to wait for planes on the tarmac because of high winds

Seats can use more cushioning, it felt very hard. The snack option could be better

The plane from Calgary to Comox was incredibly warm, with little to no air flow and when served drinks there was like 2 ice cubes that melted instantly. Everyone was using the plastic menus to fan themselves. Awful

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Almost everything it was a “cool” ambiance but we arrived to Toronto so that it’s ok for me

Front desk attendant wouldn’t check me in even though there was not a single person in line. Made me use the kiosk. Kiosk had an error (of course) no baggage can be checked at this kiosk please see attendant. Then I had to wait in line for the same front desk attendant waiting for 5 people who ended up coming in front of me while I tried to use a broken and useless kiosk. Finally after checked in, wait 30 min to board all the way to zone 6 and they would deny me even after all the zone 1-5 people already went. Just literally making us wait to board so they stand there doing nothing for 5 minutes. Just ridiculous and awful customer service. Fly with literally anyone else

Small plane with no space, old seats, no entertainment, big turbulences

Another 5h flight with Air Canada with no screens and WiFi not working. Not even intranet for inflight movies on personal devices. UNACCEPTABLE

I would prefer if the Exit row seating was treated as priority seating.

I would never fly air Canada again….delay after delay…poor service….

A coffee in the morning before we land would have been very appreciated.

The crew was nice and helpful. Seats were basic. For a 4 hour flight, they didn’t even offer snack. Just paid snack, which is lame.

Check-in was excellent. Flight crew were average, but managed the weather induced stress calmly. We were delayed five hours due to weather, equipment, and staffing shortages.
