Seoul to Buenos Aires (Ezeiza)
24h 37mgate to gate
The flight from Incheon International Airport (ICN) to Ezeiza International Airport - Ministro Pistarini (EZE) covers 19,479 km (12,104 miles) and takes approximately 24h 37m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 58°, passing near 26.3° N, 124.9° W at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 19,479 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 24h 12m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 24h 37m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
19,479 km / 805 km/h = 24h 12m airborne
+ 25 min ground = 24h 37m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 | 35h 25m | 35h 50m |
| Narrowbody jet (A320, 737) | 780 km/h | 24h 58m | 25h 24m |
| Widebody jet (777, 787, A350) | 900 km/h | 21h 39m | 22h 04m |
| Private jet (Gulfstream) | 850 km/h | 22h 55m | 23h 20m |
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 this plate answers
How long is the flight from Seoul to Buenos Aires (Ezeiza)?
A non-stop flight from Seoul (ICN) to Buenos Aires (Ezeiza) (EZE) takes about 24h 37m. The great-circle distance is 19,479 km (12,104 miles, 10,518 nautical miles), flying north-east on an initial bearing of 58°.
How far is Seoul from Buenos Aires (Ezeiza)?
19,479 kilometres in a straight line over the earth's surface — 12,104 miles or 10,518 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 EZE?
This page calculates the direct-line time and distance; it does not track airline schedules. At 19,479 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 24h 37m 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.
