Reviews of the top 5 airlines flying to South Korea
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
Not many people, so you can lay down on two seats
The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.
long flights are difficult but the crew and amenities made it a very good experience
Comfortable seats but I had a hard time with the reclining pull.
Reasonable fair, good service, in sum, I am very happy!
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.
Great airline, but there was no English entertainment (movies or shows)
One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.
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?
Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.
Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.
Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.
The staff hold my luggage to steel and exchange my stub, i was very disappointed.
Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.
Customer service and attention to details. The food was good.
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.
My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.
Love flying Asiana. Been using it for over a decade now.
Flights were on time, my connecting gate was VERY close to my arrival gate, everything went smooth and made for a delightful experience.
The flight was freezing cold. I had on pants and a sweatshirt, had to wrap up in the blanket provided AND put on my rain coat, and was still chilly. Have never been on such a cold plane.
The flight was delayed to board, then delay in landing and extremely bumpy landing.
Late flight, screens not working and still had to pay for a drink
great! appreciated the last minute upgrade to Comfort+ exit row, as well
Crew completed ignored our aisle when giving snacks and coffee
I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.
A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed
The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.
All in all it was a long flight in economy class. There’s only so much comfort one can expect on a plane. The seats felt exceptionally hard and as an over 6’ individual I’ll seldom feel great about legroom. The food was good and the flight crew was great. The headphones provided for the movies were terrible, though
On time. Carry on and personal bag was accommodated on the plane. Entertainment was accessible without bringing own device. Whole can of juice was provided rather than a pour.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.
I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.
Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.
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.
The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!
When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!
Price was crazy watch it if you Chan he your flight
United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.
