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 | 17h 35m | 18h 00m |
| Narrowbody jet (A320, 737) | 780 km/h | 12h 24m | 12h 49m |
| Widebody jet (777, 787, A350) | 900 km/h | 10h 45m | 11h 10m |
| Private jet (Gulfstream) | 850 km/h | 11h 22m | 11h 48m |
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 Las Vegas?
A non-stop flight from Seoul (ICN) to Las Vegas (LAS) takes about 12h 26m. The great-circle distance is 9,668 km (6,008 miles, 5,220 nautical miles), flying north-east on an initial bearing of 45°.
How far is Seoul from Las Vegas?
9,668 kilometres in a straight line over the earth's surface — 6,008 miles or 5,220 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 LAS?
This page calculates the direct-line time and distance; it does not track airline schedules. At 9,668 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 12h 26m 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.
