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 screen was broken so now movies, etc, but I didn’t really mind. They did work on it, so good effort on their part.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

The Turkish was good . I had a problem with air Transat terrible experience for me

Very good. A lot better experience then I expected for an economy flight.

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Clean plane. Departed ahead of schedule, arrived early. Captain was informative- could clearly hear announcements and flight went as he told us. Could use some simple snack with free beverages. Consider comp with-go on planes.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

No snacks served! Seating in the kast row in uncomfortable.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

The trip from LAX to Calgary was aboard a 737-700, which is more than twenty years old. Service was fine, and the food was good, but there was no inflight entertainment, and no WiFi. The flight from Calgary to Vancouver was also delayed more than an hour, due to congestion on the Calgary tarmac. And no food service, but there was in-flight WiFi which made a big difference.

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

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.

The flight was ahead of schedule. A half glass of juice and a cookie is pathetic! No entertainment possibilities. Not even a plug-in for phone or IPad if you wanted to watch a downloaded movie. Back to flying Air Canada!

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

Plane should have entertainment, instead of people paying to use wifi

Flight was delayed. Arrived in Vancouver at 3 am. Not a great experience.

Flight was delayed 1.5 hours. Baggage took 45 minutes to reach carousel

The quality of service at WestJet has really decline in the past couple years. Now they rarely leave on time and are full of excuses to obviously try to minimize their responsibility for compensation. Reality and what is mentioned at the gate for delaus rarely jive. If you apply for compensation even if appropriate, you are declined. They need to get back to doing the small things great rather than look for more reasons to grab money.

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 left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

The crew was really nice. The plane seats were kinda small even for a 5’6” / 158 lbs person.

Re luggage I carried a backpack only. I did not check any bags in. However there were other passengers with carry on luggage going in the plane. My question is why are others allowed to have a carry on luggage inside the plane? Shouldn’t they have dropped it off at the gate? I’m asking because I could have brought the same thing instead of a backpack only. Please clarify for future reference. Thank you.

Like the service. Very hard to communicate or contact when have problems

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

Very pleasant crew! Good entertainment options. Water wasn’t working in the bathrooms, but they were able to fix it. Just had to stand with sticky soap hands for 20min….

I did not appreciate being scolded by the captain himself, and being told my dog could die, in front of my daughter.

My flight from LAX to toronto, of 6 hrs, and no food was served. I expected lunch but they gave only a soft drink and a biscut. Very sorry to say it was terrible.

Our first flight to Toronto was awesome. Especially because of the flight attendant. She treated my kids and I so well and was so kind to my little 5 year old birthday boy. The smiles and kindness she shared with us made it everything for my kids to fly with Air Canada. But our second connecting flight didn’t have any entertainment or TVs and the crew was okay. Not great but just okay
