Los Angeles to Sepang
18h 01mgate to gate
The flight from Los Angeles International Airport (LAX) to Kuala Lumpur International Airport (KUL) covers 14,163 km (8,800 miles) and takes approximately 18h 01m gate to gate for a typical jet.
The route heads north-west on an initial great-circle bearing of 306°, passing near 43.1° N, 157.4° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 14,163 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 17h 36m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 18h 01m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
14,163 km / 805 km/h = 17h 36m airborne
+ 25 min ground = 18h 01m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 this plate answers
How long is the flight from Los Angeles to Sepang?
A non-stop flight from Los Angeles (LAX) to Sepang (KUL) takes about 18h 01m. The great-circle distance is 14,163 km (8,800 miles, 7,647 nautical miles), flying north-west on an initial bearing of 306°.
How far is Los Angeles from Sepang?
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 LAX and KUL?
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.
