14h 41m The flight from Incheon International Airport (ICN) to Hartsfield Jackson Atlanta International Airport (ATL) covers 11,487 km (7,138 miles) and takes approximately 14h 41m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 26°, passing near 69.5° N, 154.0° W at its midpoint.
The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 20h 53m | 21h 18m |
| Narrowbody jet (A320, 737) | 780 km/h | 14h 44m | 15h 09m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 46m | 13h 11m |
| Private jet (Gulfstream) | 850 km/h | 13h 31m | 13h 56m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions
How long is the flight from Seoul to Atlanta?
A non-stop flight from Seoul (ICN) to Atlanta (ATL) takes about 14h 41m. The great-circle distance is 11,487 km (7,138 miles, 6,203 nautical miles), flying north-east on an initial bearing of 26°.
How far is Seoul from Atlanta?
11,487 kilometres in a straight line over the earth's surface — 7,138 miles or 6,203 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between ICN and ATL?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,487 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 14h 41m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
