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.

Flight was delayed over 2 hours, then landed at a different airport!

Upset about cancel to St. John’s and no overnight accomodation

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

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

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

Not United Airlines' fault. It's ORL airport's fault.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Flight was cancelled due to a myriad of operational issues. You guys really suck

Our gate was changed several times, and the gate agents were just as in the dark as all of us in knowing when our plane would arrive at PHL.

mechanical problem delayed more than 2 hours on the run way.

The boarding process was slow and we had a delay on the tarmac, not the fault of the airline. They had ZERO food options available for purchase which shouldn't happen.

The flight had a 6 hours delay. This should not happen to anyone. Airlines should provide an alternative with no additional costs.

Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.

American notified via app that the flight was delayed. However, when I went to the gate, they were already boarding and had not updated communications that they had pulled the flight time back. They made the entire flight re-check in which by this time I had lost my exit row seat and ended up in a middle seat. As a 4 decade flyer of American and Exec Plat, my expectations for the company are that the customer service would be better. This unfortunately is no longer a strong point for any of the major airlines including American. They are basically city buses flying at 30 thousand feet.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Was a normal flight but it was delayed, and there wasn't an explanation.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

Most courteous, helpful employees and all flights were on time.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

No complaints l will always do Air Canada once they are flying where I want to go

Flight was delayed an ultimately cancelled. Took me close to 45 mins with an Air Canada staff to be put on another flight.

I was unaware I was booking the basic economy flight and had to spend an extra $125 for baggage plus $100 for seat selection. There was also no opportunity to upgrade into a different ticket type. The seats were very cramped and mine wouldn’t stay reclined

Air Canada staff needs to be trained in hospitality. Most flight attendants are with attitude. Air Canada needs to carry additional food on board especially vegetarian plates as this category of travellers are on the rise. This is necessary for long distance flights. Blankets are cheap. Seats are not designed well Lower back portion should be thicker. Everytime thr passenger at the back of me took stuff or put stuff in the pocket of the seat in front of them which is my seat, I could feel them pushing or hitting on my chair.

There was no one at the check in desk so I missed my flight. I wasn’t able to reschedule business class and had to pay about $2300 extra to rebook premium economy. Almost ruined my trip!

The walk from arrival terminal to international departure terminal is very, very, very long. If more golf carts were available for tight connections, that would be a welcome improvement.
