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 18m | 33h 43m |
| Narrowbody jet (A320, 737) | 780 km/h | 23h 29m | 23h 54m |
| Widebody jet (777, 787, A350) | 900 km/h | 20h 21m | 20h 46m |
| Private jet (Gulfstream) | 850 km/h | 21h 33m | 21h 58m |
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 São Paulo?
A non-stop flight from Seoul (ICN) to São Paulo (GRU) takes about 23h 10m. The great-circle distance is 18,314 km (11,380 miles, 9,889 nautical miles), flying north-west on an initial bearing of 335°.
How far is Seoul from São Paulo?
18,314 kilometres in a straight line over the earth's surface — 11,380 miles or 9,889 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 GRU?
This page calculates the direct-line time and distance; it does not track airline schedules. At 18,314 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 10m 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.
