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 | 14h 59m | 15h 24m |
| Narrowbody jet (A320, 737) | 780 km/h | 10h 34m | 10h 59m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 09m | 9h 34m |
| Private jet (Gulfstream) | 850 km/h | 9h 41m | 10h 07m |
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 Prague?
A non-stop flight from Seoul (ICN) to Prague (PRG) takes about 10h 39m. The great-circle distance is 8,237 km (5,118 miles, 4,447 nautical miles), flying north-west on an initial bearing of 322°.
How far is Seoul from Prague?
8,237 kilometres in a straight line over the earth's surface — 5,118 miles or 4,447 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 PRG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,237 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 10h 39m 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.
