The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.
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 was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me
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
long flights are difficult but the crew and amenities made it a very good experience
Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.
They destroyed my Michael Kors Carryon luggage, they didn’t announce that only check in the carry on and when we get inside a couple of room to put the carry on bag. I was disappointed and sad because of the damaged of my luggage. They should replace it or fixed it.
Comfortable seats but I had a hard time with the reclining pull.
Seating was good in the economy with plenty of leg room. The seat cushions were a little firm though, especially for such a long flight. All meals were Korean as would be expected. The food was typical airline quality. Edible, but not something you would recommend to friends. Inflight entertainment was also all Korean but Korean tv and movies are made well and you can find something to watch. Just be prepared to read subtitles. Overall it was a good flight, especially for the price.
The person in front of me was rude. He may came from some communism countries and don’t care of other people. No common manner and sense between human being.
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.
Plane and service were great. The entertainment is only for Koreans. Wish there were vegetarian options for food. All in all pleasantly surprised. Economy premium was quite good.
Some favorite food ran out of service and I have to eat what was left available. Also I had to drink cold red wind! Why could not have been kept in room temperature?
Plan was very clean and very comfortable seat Very smooth flight without any engine noises.
The leg space is generous at 35 inches. The food is quite limited with one breakfast, one lunch and 1 snack throughout the 14 hr trip. The entrainment state is big fallout with only a handful of movies, all Korean. Quite a few of them are not for kids for sure. And the onboard paid wifi is not working, not sure whether it is just for this flt, which prevents you from entertaining yourself. The flt attendant speaks little language other than Korean. The biggest drawback with this new airline is that it does not have any partnership with other airlines so if you are connecting in Seoul, your luggage is not transferred. And you have to get into the custom, pick it up then check in with other airline, which requires very long layover to manage the connection. We planned 3.5 hr layover, with flt delayed 2.5 hrs, we missed the connection flt with one hr left in between. In summary, if no connection is needed for your itinerary and you are Korean, air premia is a good option with competitive price. Otherwise, go with one of the major carriers.
Food is very little, we were hungry again afterward. 💺 is very small not comfortable. Very helpful staffs at check in counter.
I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.
It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.
Love flying Asiana. Been using it for over a decade now.
The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.
For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.
Only process that my luggage didn’t make it to my destination because of short connection but I understand
I like the food, the crew and everything.!!! Except for the delay in our flight.
Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️
My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.
I recently had the pleasure of flying with Asiana Airlines, and I can confidently say it was an outstanding experience. From the moment I checked in, the staff demonstrated exceptional professionalism and warmth. The boarding process was seamless and well-organized, ensuring a stress-free start to my journey. Onboard, the flight attendants were attentive, courteous, and went above and beyond to cater to passengers' needs. The seats were comfortable, with ample legroom, and the in-flight entertainment options were diverse and up-to-date, making the flight enjoyable and relaxing. Additionally, the meals served were delicious and well-presented, reflecting a high standard of culinary quality. The airline's commitment to safety was evident throughout the flight, with clear announcements and a reassuring presence from the crew. Overall, Asiana Airlines provided a top-tier travel experience, and I would highly recommend them to anyone seeking comfort, quality service, and a memorable journey.
WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience
The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.
Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.
Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.
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.
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.
Flight was over two hours late, but they notified us early in the morning. They ended up changing planes the food on board that was extremely mediocre and we were in premier class.
Food was very bad Crew was not so welcoming. Chairs was so uncomfortable
The business class had to wait to board last. Unacceptable
The air hostess was excellent. I have taken so many flight domestic and international, this is the first time the air hostess was so caring. She was a delight
We paid extra to check our bags ($90*2=$180) but our luggage remained in Frankfurt. VERY DISAPPOINTED as we were promised that our luggage would go to our destination. We had to pay 90€ to take a taxi back to the airport in Split the next day to get our bags so we would not miss our next step on our trip. We think we should be reimbursed for our checked bags. How can we coordinate this?
This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.
Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.
United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.
