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 | 10h 29m | 10h 54m |
| Narrowbody jet (A320, 737) | 780 km/h | 7h 24m | 7h 49m |
| Widebody jet (777, 787, A350) | 900 km/h | 6h 25m | 6h 50m |
| Private jet (Gulfstream) | 850 km/h | 6h 47m | 7h 12m |
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 Colombo?
A non-stop flight from Seoul (ICN) to Colombo (CMB) takes about 7h 35m. The great-circle distance is 5,768 km (3,584 miles, 3,114 nautical miles), flying south-west on an initial bearing of 246°.
How far is Seoul from Colombo?
5,768 kilometres in a straight line over the earth's surface — 3,584 miles or 3,114 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 CMB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 5,768 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 7h 35m 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.
