Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

Korean air has a little bit more seating space than Asiana air.

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Food quality is poor. Flight attendants are very friendly and professional.

I flew on Zip Air on the way to Asia so I can compare. The two airlines are night and day. Air Premia was so amazing compared to Zip Air. I have flown Korean Air in the past and I honestly don’t know the difference between Air Premia and the “non-budget” airlines. My Air Premia flight provided me two bags whereas I had to pay for Zip Air. On my under 11 hour flight, we were provided two full meals! The flight attendants were so kind and polite.

For the price, the overall experience was what I expected. The prices were fair and competitive, the staff friendly and more responsive than other airlines, and seating spacious. The downside was food portion size, but I'll gladly pay a few dollars more for the hot noodles or other supplemental snacks, given the more affordable ticket prices. I don't mind the absence of Hollywood movie programming if that leads to inflated ticket prices. Wi-Fi worked well. In addition to spacious seating for the Wide Premiium, I'd suggest foot rests to complement the calf rests. There're problems with booking Air Premia tickets at the home website. The underlying app engine won't process non-Korean credit cards, which is a major oversight, probably hurting the company's bottom line. I can go to Kayak or a third-party website to book Air Premia tickets, but it's an awkward work-around when other airlines don't have to resort to this tactic.

As it's a budget airline it's pretty basic. But the quality of crew and plane is excellent.

First time flying with them and was pleasantly surprised. I had a premium economy seat which is very similar to some other airlines regional business class product. Seat was large, pillow was provided, huge amount of leg room, entertainment was available (only Korean shows), and lunch meal was served between Narita and Seoul. Really enjoyable and affordable

Maybe the reimbursement voucher should have been larger than a 10k won. That voucher is only for refreshments. The flight was delayed or pushed to more than 5 hours. It should be more than just 10k won and it was already past midnight. Some people or passengers like who was already there 5 hours prior to the original flight departure. 4pm** That was the only unfortunate thing about it . Other than that it was good .

5 hour delay, therefore, middle of the night arrival doesn’t help.

The staff were very friendly, and the flight was comfortable. That said, there was no option to specify dietary restrictions before the flight, so you may need to bring your own food. Also, there was no wifi available for the flight, though there is an in-flight entertainment console with many Korean-language shows and movies.

The legroom was great for a 5’11” person. The 11 hour direct flight had two meal services included in the ticket price which was less than other airline’s cost without food service (Canada air)from sfo to incheon. The airline is focused towards Korean nationals with the onboard entertainment selection of Korean movies but English subtitles were available. Overall premia air is a great option to fly from the US to Korea.

Most of them are OK! But, meals service was not enough. I felt hungry after eating the meal for the first time. I had to buy some other food. So I had to buy a sandwich and drinks for the return flight. And I am not sure it's only my feeling or not, I felt my butt is getting forward. I will use Korean Air or Asiana Airline for next time to visit Korea.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

Boarding was organized. Old plane. Seat fairly comfortable. Business Class much too large so you don’t receive as much attention as you should considering what you pay for the seat.

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.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

The food should improve! And The flight should leave on time and not make the traveler wait.

We love united ! We would like to acknowledge Aimee in the lounge near gate 130

Survey sent before we actually left. Delay after delay. Now a crew problem.

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

Allow me to book extra bag check in as free though I packed in 1 luggage but that was 7 LBS overweight so make another bag to free check in.

My flight from New York to Canada and Canada to Brisbane was canceled, so I had to take united airlines instead flight from New York to Dubai then layover in Dubai 8 hours then from Dubai to Brisbane it was extremely difficult for me , it was a nightmare flying with Canadian airlines unfortunately.

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.

Strike pissed me n stranded in middle of no where

Refreshments and Air Hostess was good. Issues with customs in Toronto caused flight to depart and left me behind twice. Vouchers for delayed flight needs to increase.

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

Everything was good till we got to yyz...then we got to the gate and there was NO GATE AGENT. We waited 15 min before disembarking. No internet No IFE Old aircraft Second leg in two weeks NOT IMPRESSED

The seats are soooooooo small in economy. I was offered no tea or coffee in the am. When I asked was told that it was too late. The plane was 2 hours late leaving.

My first flight left so late we knew I would miss my connection. Rather than redirecting me then, they made me take a flight to Montreal, then Toronto (there was a flight leaving for Toronto when I was in NYC, no need for me to also go to montreal). Then they gave me a food voucher that did not work (4 places would not accept it). At least they gave me a hotel automatically, even though it was a cheap crappy one. I'm still not home, and it's been over 24 hours. I'm exhausted.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!
