Korean Air connects the US to Jeju, 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)
From JFK, Korean Air takes you nonstop to Seoul Incheon (about 14 hours), then a domestic flight to Jeju adds roughly 70 minutes. Total door-to-door time with the layover is around 18-19 hours.
Los Angeles International Airport (LAX)
LAX passengers fly nonstop to Seoul in about 13 hours, then connect to the frequent Seoul-Jeju domestic shuttle. This is one of the busiest domestic air routes in the world, so connections are plentiful.
San Francisco International Airport (SFO)
San Francisco to Jeju via Seoul takes about 16-17 hours total. Korean Air coordinates domestic connections to keep layover times short.
Seattle-Tacoma International Airport (SEA)
Seattle's shorter flight to Seoul (about 12 hours) makes the total trip to Jeju around 15-16 hours.
O'Hare International Airport (ORD)
Chicago to Jeju via Seoul runs about 18-19 hours total. The Seoul-Jeju route has dozens of daily flights.
Hartsfield-Jackson Atlanta International Airport (ATL)
Atlanta passengers connect through Seoul with a total journey time of about 19-20 hours.
Cheapest Months to Travel
November through February is low season for Jeju, with the cheapest fares. The island is a summer destination for Korean tourists, so winter months are quiet and affordable.
Peak Travel Seasons to Avoid
July and August are the most expensive months, followed by cherry blossom season in late March through April.
Best Time to Book
Book the international leg 8-12 weeks ahead. The Seoul-Jeju domestic segment has high frequency, so availability is rarely an issue.
Midweek Advantage
Midweek departures from the US save money on the long-haul leg. For the Seoul-Jeju domestic flight, weekday travel is cheaper.
Time Difference to Keep in Mind
Jeju follows Korea Standard Time (KST), same as Seoul. That's +14 hours ahead of Eastern Time, +17 ahead of Pacific Time.
