FAQs - booking South Korea flights

  • Are there nonstop flights to South Korea?

    There are several nonstop flights to South Korea from US cities like Los Angeles, Seattle, San Francisco, Honolulu, Chicago, New York and other major cities, but only if you’re traveling to Seoul. Flying to other areas in Korea from the US will involve at least one stop, with common layover points including Seoul, Taipei and Hong Kong.

  • Is a visa necessary to visit South Korea?

    United States citizens can visit South Korea for up to 90 days without a visa; however, you must present a passport that’s valid for the entire duration of your stay when you arrive in South Korea.

  • Where should I fly into South Korea to be convenient to Japan?

    If you’ll be traveling on to Japan after spending time in South Korea, flying to Busan will set you up for a convenient onward flight. Busan is located on the southern coast of South Korea and is located only 519 mi away from Japan. Flights between Busan and Fukuoka are generally less than 1h long and operate via Air Busan, Korean Air and Jeju Air.

  • Which Seoul airport should I fly into?

    There are two large airports in Seoul: Seoul Incheon Airport (ICN) and Gimpo Airport (GMP). Incheon is a little further away from Seoul than Gimpo, but you’re unlikely to find a flight from the United States that arrives in Gimpo, often making it the only choice unless you’re making a stop between the US and South Korea.

  • Which nearby cities are accessible to visitors arriving at the Gimpo International Airport (GMP) in South Korea?

    Travelers are able to explore a few additional sites close to GMP Airport. You can take a taxi, hire a car, or take public transit from the GMP Airport to the adjacent cities of Bucheon, Gwangmyeong, Goyang, and Incheon. Each of the aforementioned cities' central business districts are fewer than 19 miles from GMP.

  • If I want to be close to sporting events in South Korea, which airport should I use as my arrival point?

    When visiting South Korea, American sports enthusiasts should think about flying into Gimhae International Airport (PUS). Busan Asiad Main Stadium, Gudeok Stadium, and Sajik Baseball Stadium are stadiums close to PUS that hosts international and domestic sporting events, particularly on weekends.

  • Are there any specific services or rules for bringing pets on the flight to KR0 from USO?

    Yes. When traveling to South Korea on the USO-KR0 route, passengers do not need to worry about the security of their dogs. The majority of US airports, like Los Angeles International Airport (LAX) and JFK, that provide USA-South Korea flights permit visitors to enter the airport with their pets.

  • Which airport in the northwest of the United States has the most visitors going to South Korea?

    The majority of Americans traveling from the country's northwest to South Korea prefer to fly through Seattle-Tacoma International Airport (SEA). Unfortunately, there are currently no direct flights connecting SEA with KR0. Passengers can only take indirect flights.

  • How does KAYAK find such low prices on flights from the United States to South Korea?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to South Korea.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United States to South Korea?

  • What is the Hacker Fare option on flights from the United States to South Korea?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to South Korea with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to South Korea?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to South Korea up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest South Korea flight deals.
  • When you’re booking your flight to South Korea from the US, there are a few different cities you can fly into. Seoul and Busan are the biggest cities in South Korea, making them popular choices to fly into. Flying into Seoul will give you better access to northern South Korea and Busan will give you better access to southern South Korea.
  • While some hotels in South Korea may accept US Dollars, you can often get a better rate by using the country’s local currency: The South Korean Won. Visa and Mastercard are accepted by most businesses, though it can be handy to have some cash on hand for street vendors and other instances where cards aren’t readily accepted.
  • For travelers looking to visit the border with North Korea, you’ll benefit by flying into Seoul. Most of the international flight traffic from South Korea to the United States comes through Seoul and flying there puts you in close proximity to the DMZ. From Seoul you can take the designated DMZ Peace Train straight to the Demilitarized Zone.
  • If you’re looking to fly into a city where you can have equal access to the rest of South Korea, it can be handy to fly into Daegu. Not only is Daegu a popular destination and a major South Korean city, it is located conveniently towards the center of the country.
  • Jeju Island is one of South Korea’s most popular tourist destinations outside of the major cities, and there are a few different ways to get there. You can take a flight to Jeju from the US, with a likely layover in Taipei or Seoul, or you can fly to Busan and take a ferry the rest of the way.
  • The majority of Americans who visit South Korea choose to fly through John F. Kennedy International Airport (JFK). This airport is well-liked since it serves as a hub for so many reputable airlines that fly internationally from the United States. Due to pricing competition, travelers departing from this airport for South Korea are likely to receive ticket discounts.
  • If your flight from the US is planned to land in South Korea at night and you're taking the Incheon International Airport (ICN) from the JFK route, you might want to think about reserving a hotel next to the ICN Airport. Choosing the Incheon Airport Transit Hotel, located at Terminal 1, is one of the best considerations. This airport provides a complimentary shuttle service to and from ICN Airport.
  • The best option for US parents who want to take their kids on holiday to South Korea is likely to be a flight on Korean Air 86, Asiana 221, or Korean Air 82 through JFK to ICN. Non-stop flights from the USA to South Korea are available year-round from this airport. There is a lower likelihood that your children will be exhausted before landing in South Korea from the USA thanks to the availability of direct flights, which make it possible for travelers to get there in the minimum period of time.
  • The best spot for travelers to unwind while waiting for a flight to their intended destinations is in airport lounges. The majority of low-cost American passengers who want to unwind in an airport lounge on their way to South Korea opt to depart through Salt Lake City International Airport (SLC). Travelers on a tight budget can comfortably relax at Delta Sky Club at the SLC Airport, which provides first-rate amenities at a competitive price.
  • Passengers suffering from mobility challenges need to think about departing from JFK Airport and landing at Jeju International Airport (CJU) when going to South Korea. Visitors with particular requirements and mobility issues can request free aid with their bags, medical support, plus wheelchair transfer from a cab to an aircraft at JFK and CJU Airports.

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.

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!

Very nice staff, airplanes, and an excellent value in premium economy.

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.

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.

Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Premium Plus is a really good idea for longer flights

Over 40 years ago my AC return flight was canceled, during this last summer the same thing happened. AC denied everything Canadian like paying for accommodations and basic necessities. So why would I ever want to fly AC again? This last flight my wife took the return flight had problems and left late, so I guess they are getting better. However I have no faith in this airline so I drove to this last destination! I'll never fly AC again!!!

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

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.

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

Boarding was so so after zone 3 was called all other zones went in

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.
