23h 16m The flight from Incheon International Airport (ICN) to Comodoro Arturo Merino Benítez International Airport (SCL) covers 18,392 km (11,428 miles) and takes approximately 23h 16m gate to gate for a typical jet.
The route heads east on an initial great-circle bearing of 79°, passing near 13.2° N, 142.7° 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 | 33h 26m | 33h 52m |
| Narrowbody jet (A320, 737) | 780 km/h | 23h 35m | 24h 00m |
| Widebody jet (777, 787, A350) | 900 km/h | 20h 26m | 20h 51m |
| Private jet (Gulfstream) | 850 km/h | 21h 38m | 22h 03m |
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 Santiago?
A non-stop flight from Seoul (ICN) to Santiago (SCL) takes about 23h 16m. The great-circle distance is 18,392 km (11,428 miles, 9,931 nautical miles), flying east on an initial bearing of 79°.
How far is Seoul from Santiago?
18,392 kilometres in a straight line over the earth's surface — 11,428 miles or 9,931 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 SCL?
This page calculates the direct-line time and distance; it does not track airline schedules. At 18,392 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 23h 16m 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.
