Flights From Atlanta to Seoul, South Korea: A Complete Guide for ATL Travelers

Planning a trip from Atlanta to Seoul, South Korea? Whether you live in metro Atlanta, are flying out of Hartsfield–Jackson Atlanta International Airport (ATL) for the first time, or you’re here on business and heading onward to Asia, this guide walks you through what to expect and how to plan your flight.

Overview: Getting From Atlanta to Seoul

Flights from Atlanta to Seoul (Incheon International Airport – ICN) are long-haul international routes, typically around 14–16 hours of total travel time depending on whether you choose a nonstop or connecting flight.

For most Atlanta-based travelers, the key choices are:

• Nonstop flights: Atlanta (ATL) → Seoul (ICN)
• One-stop flights through major hubs such as Dallas, Chicago, New York, Detroit, Los Angeles, San Francisco, or international hubs like Tokyo, Vancouver, or Doha

If you live in Atlanta or nearby areas (Decatur, Marietta, Duluth, Lawrenceville), using ATL will almost always be your most practical departure point.
