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

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.

Flight delayed by half hour, causing rush to get to connecting flight in Toronto Pearson which doesn’t have good flow for managing immigration check and connections.

Crew is ok. They offered food n drinks. Had difficulty connecting to wifi on board.

Flight was smooth and comfortable. The crew were exceptional. Amanda, Nichole and Hershel were attentive to our every need. So friendly. My daughter and I were surprised at quality of service. Loved the double row seating. Snacks were delicious. We would definitely fly with Porter again. Flight PD 670 SFO to YYZ Thank you so much for the best flight experience we have had

My son’s suitcase was left behind at SFO and did not make the flight.

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

Flight delayed four separate times. I’m now one hour hours late to landing.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

The pilot was late so we didn’t take off til almost 2 hours late.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Excellent communication from the staff. We actually arrived early. Very friendly and professional staff.

Some crew were unfriendly or in some cases just straight up rude.

Entertainment kept turning itself off. Gave up on watching a movie.

From the first moment you interact with United Airlines, you can expect nothing less but extreme frustration. The baggage handler at the bag drop seems completely unbothered by the presence of customers waiting in line. No help was extended to load the baggage whatsoever. And if any of your bags is overweight by 0.01 pound they will make you re-distribute everything in your suitcase just to play power trip. When it was time to board no help was extended to customers to locate their seats. Moreover. It was a chaotic mess at the gate when it was unclear who should board first and everyone just bunched up, trying to get on the plane. I am sure the crew was doing their best to perform their jobs while being paid their wages however it shouldn’t be that hard to smile once or twice when you’re in the business if serving customers. It is a shame for the United States of America to have a flagship carrier of such low caliber. Our flight was also delayed by about an hour and a half due to further delays prior to our inbound flight. Being someone who has travelled for both business and leisure in Asia, Europe, and South America I have never experienced such poor quality of service.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

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,

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!

They lost my bag. Hopefully it will be here tomorrow.

Kayak was the problem! The tickets we bought did not allow for carry on or checked luggage and we ended up paying more for those services than the tickets! The paperwork Kayak provided for the receipt left the luggage policy for Westair intentionally blank. This was intentionally decietful on Kayak's part. Our additional cost was over $400.00! I will be calling customer service today asking for refunds and I will keep you informed on any review sites as I can. Keith

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

The flight was on time - which is good. But pretty much every other aspect of the experience was bad. They charged 55$ for a carry on bag!

Flight was old and the seats were not comfortable at all. They made me pay 55$ to take my carry-on bag onboard.

The seats were very comfortable. However the meal on the transatlantic portion of the trip was not very good, even by airline food standards.

They made my minor daughter leave the area and go back though security during a flight connection with her checked luggage

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

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

Bad experience boarding and flight got delayed didn’t make it to my next flight

The fact that we have to check in our carryons when we met the requirements and there was plenty of spaces near we sat was ridiculous

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

This is the first and the last time I ever fly Air Canada. The seats were extremely uncomfortable, no leg room. My back was throbbing by the time the flight was over. I payed both flights up and back for internet and both times had trouble connecting all while the clock was ticking on my payed subscription. Here's the worst part which I have never experienced on a flight before. the flight attendant would walk down the aisle with the drink cart and only give out drinks to selected passengers. This was not a big plane, there were not that many passengers! We were totally ignored, I had to ask three times for my husband to get a drink. My son and his girlfriend were sitting across the isle from us and received a snack but we were never offered a snack or anything. My son's girlfriend had children sitting behind her who were continually kicking her seat the entire flight. I have never wrote a negative review for an airline before but after spending my money for four seats I was extremely disappointed in your service.

Flight was canceled 2 hours ahead. Just as I arrived at the airport
