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 | 25h 45m | 26h 10m |
| Narrowbody jet (A320, 737) | 780 km/h | 18h 09m | 18h 35m |
| Widebody jet (777, 787, A350) | 900 km/h | 15h 44m | 16h 09m |
| Private jet (Gulfstream) | 850 km/h | 16h 40m | 17h 05m |
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 Los Angeles?
A non-stop flight from Sepang (KUL) to Los Angeles (LAX) takes about 18h 01m. The great-circle distance is 14,163 km (8,800 miles, 7,647 nautical miles), flying north-east on an initial bearing of 42°.
How far is Sepang from Los Angeles?
14,163 kilometres in a straight line over the earth's surface — 8,800 miles or 7,647 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 LAX?
This page calculates the direct-line time and distance; it does not track airline schedules. At 14,163 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 18h 01m 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.
