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).

    Travelers are able to explore a few additional sites close to GMP Airport.

Each of the aforementioned cities' central business districts are fewer than 19 miles from GMP.

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.
