Booking
Korean Air connects the US to Busan, South Korea, through its Seoul Incheon hub with daily service from cities like New York, Los Angeles, San Francisco, and Seattle. The routing via Seoul adds a connection but gives you access to Korean Air's award-winning cabins and competitive pricing. We can help you find the best fares and fastest connections.
John F. Kennedy International Airport (JFK)
Fly Korean Air from JFK to Busan with a connection at Seoul Incheon. The US-Seoul leg runs nonstop at about 14 hours, then the domestic hop to Busan takes around 55 minutes. Total travel time comes to roughly 17-18 hours including the layover.
Los Angeles International Airport (LAX)
From LAX, Korean Air connects you to Busan through Seoul. The nonstop leg to Incheon is about 13 hours, followed by a short domestic flight to Gimhae. Total journey is around 16-17 hours with a typical 2-hour connection.
San Francisco International Airport (SFO)
San Francisco passengers reach Busan via Korean Air's nonstop service to Seoul, then connect on a domestic flight. Total trip runs about 16-17 hours.
Seattle-Tacoma International Airport (SEA)
Seattle is one of the closest US cities to Seoul, with a nonstop flight of about 12 hours. Add the Seoul-Busan domestic connection and you're looking at around 15-16 hours total.
O'Hare International Airport (ORD)
From Chicago, Korean Air routes you through Seoul Incheon before the short domestic flight to Busan. Total travel time is about 18 hours.
Hartsfield-Jackson Atlanta International Airport (ATL)
Atlanta passengers fly nonstop to Seoul on Korean Air, then connect to Busan. Total journey is roughly 18-19 hours.
Cheapest Months to Travel
January, February, and October typically offer lower fares. Busan is a beach destination, so summer months drive up demand.
Peak Travel Seasons to Avoid
July and August are peak season for Busan due to beach tourism. Korean holidays like Chuseok increase domestic flight costs too.
Best Time to Book
Book the US-Seoul leg 8-12 weeks out for best pricing. The domestic Seoul-Busan connection can be added at booking or purchased separately closer to travel.
Midweek Advantage
Midweek flights from the US tend to be cheaper. For the Seoul-Busan domestic segment, weekday flights also have more availability.
Time Difference to Keep in Mind
Busan is on the same time zone as Seoul, Korea Standard Time (KST), which runs +14 hours ahead of Eastern Time and +17 ahead of Pacific Time.
