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 | 13h 37m | 14h 02m |
| Narrowbody jet (A320, 737) | 780 km/h | 9h 36m | 10h 01m |
| Widebody jet (777, 787, A350) | 900 km/h | 8h 19m | 8h 45m |
| Private jet (Gulfstream) | 850 km/h | 8h 49m | 9h 14m |
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 Riyadh?
A non-stop flight from Seoul (ICN) to Riyadh (RUH) takes about 9h 44m. The great-circle distance is 7,492 km (4,655 miles, 4,045 nautical miles), flying west on an initial bearing of 285°.
How far is Seoul from Riyadh?
7,492 kilometres in a straight line over the earth's surface — 4,655 miles or 4,045 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 RUH?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,492 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 9h 44m 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.
