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

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Flight was delayed for about an hour but overall good experience

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

Short. Nice quick flight, appreciated after Munich to DC leg.

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Liked nothing. As per previous segment it was delay delay delay.

Extremely uncomfortable sitting in a small space for 2 hours, especially for older people. Understood it was circumstantial.

Shout out to the check in counter staff in Richmond. So pleasant and helpful with ticketing and seat selection.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Our flight was delayed 3x and we were unaware until 15min of arriving at the airport so had we been made aware sooner we could have enjoyed possibly another 4hrs poolside. Very frustrating. Made the next day going back to work extremely tough too.

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

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!

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Flight was good, crew was excellent. No complaints at all

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.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

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

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

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.

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Flight was delay for 3hours then later canceled. I missed my work. It was a bit ectic and frustrating

The flight ran out of hot meals for the back half of the plane and gave us tuna sandwiches. Not okay, these flights cost too much to short us the experience!
