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.

  • For travelers looking to visit the border with North Korea, you’ll benefit by flying into Seoul.

  • 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.

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.

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

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Not many people, so you can lay down on two seats

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.

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.

This form doesn’t work. Can’t type in, had to copy-paste. The crew constantly telling everyone about minor things is unnecessary. Did you put the belt on, push your bag more under the seat… The seat space was good for tall people, the food was decent for airplane.

Roomy seats for the given price! I couldn’t ask more!

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

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.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

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.

Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.

Real smooth and easy, Real good leg room in coach!

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Re luggage I carried a backpack only. I did not check any bags in. However there were other passengers with carry on luggage going in the plane. My question is why are others allowed to have a carry on luggage inside the plane? Shouldn’t they have dropped it off at the gate? I’m asking because I could have brought the same thing instead of a backpack only. Please clarify for future reference. Thank you.

Like the service. Very hard to communicate or contact when have problems

Very bad, flight was cancelled due to strike and staff was unable to rebook us
