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 | 19h 17m | 19h 42m |
| Narrowbody jet (A320, 737) | 780 km/h | 13h 36m | 14h 01m |
| Widebody jet (777, 787, A350) | 900 km/h | 11h 47m | 12h 12m |
| Private jet (Gulfstream) | 850 km/h | 12h 29m | 12h 54m |
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 Sepang to London?
A non-stop flight from Sepang (KUL) to London (LHR) takes about 13h 36m. The great-circle distance is 10,605 km (6,590 miles, 5,726 nautical miles), flying north-west on an initial bearing of 322°.
How far is Sepang from London?
10,605 kilometres in a straight line over the earth's surface — 6,590 miles or 5,726 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 KUL and LHR?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,605 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 13h 36m 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.
