I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

Wish we had music during take off and landing like the last flight

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

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

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Great. Porter is very efficient, welcoming, and organized. I fly Porter often.

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

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

Flight delayed 6 hr. Looking for compensation and will claim for it.allow US people to fix to avoid huge delay having a canadian tech to fix it.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

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

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

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

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

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 male air hostess was rude and didn’t even offer me a drink. Poor customer service!

We left really late. Things that were out if anybody’s control I guess.

There was no in seat entertainment, you had to spend $10 on their wifi which worked poorly at best. You were allowed ONE one oz snack for a 3.5 hour flight. Seats were made for midgets. I am a regular size adult male and I had to wedge myself in. Not a fan.

When I purchased my ticket, I assumed it was a real ticket, as in, when I go to the airport I am guaranteed a seat. Not so. When I checked in 24 hours ahead of time, I noticed I did not have a seat assignment and my boarding pass said "Standby." I was informed at the gate that the flight was full and I may not get on that plane. I don't recall being offered the option of selecting a seat when I checked in, and apparently, for the honor of pre-selecting a seat, you must pay an additional fee. So, a ticket really isn't a ticket, it's actually a lottery and if you're lucky, you may make it on board - or you can choose to be extorted for extra money for the guarantee of a seat. It's like making reservations with the Godfather - one payment isn't enough, there's always another bribe you have to make. After the first few zones were called and I hadn't been informed of my status, I went to the gate agent and they handed me a boarding pass, for the very last row near the restrooms, in between two very large people. Apparently that was my punishment for not purchasing a seat ahead of time. Airline service has not only gotten more expensive, but the return on your money has shrunk and there is little regard for the passengers. This feels like a racket. I am not pleased, as you may have gathered.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

Cabin crew were great. Seats are criminal for tall people

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped

The flight was canceled. We only found out at the airport. We had to book another flight which cost us more then the whole trip booked through Kayak. Lynx took our email and was supposed to write us with an alternate flight. We never received an email. They talked about reimbursement which was to be explained in the email (which we never received).

The online system for Lynx air to pay for additional baggage is not satisfactory. I was charged 100+$ for my suitcase when I tried to explain that the online payment was not functional using the app and showed screenshots of the same. In the end I gave up and paid and went ahead.

No snacks, just water.... could have been better. The actual flight was good.

Flight delayed by 4 hours but no communication. With passengers until after the posted departure time became apparent the flight was not going to board even close to on time.

Flight was sent canceled. The absolute most useless staff I have ever witnessed. Utterly careless - literally could not care less. 100% never using this airline again.

Poor communication at the check in counter and boarding gates.

Other then the screaming baby the flight was fine, nothing special

Check in experience was smooth, and the flight attendants were courteous and friendly. Very positive experience overall, thank you all!

Flight arrived late but other than that everything else okay

Great price for a new plane. Only offered water which we knew.
