Sepang to New York
19h 16mgate to gate
The flight from Kuala Lumpur International Airport (KUL) to John F. Kennedy International Airport (JFK) covers 15,169 km (9,426 miles) and takes approximately 19h 16m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 355°, passing near 70.4° N, 87.9° 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: 15,169 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 18h 51m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 19h 16m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
15,169 km / 805 km/h = 18h 51m airborne
+ 25 min ground = 19h 16m 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 | 27h 35m | 28h 00m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 27m | 19h 52m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 51m | 17h 16m |
| Private jet (Gulfstream) | 850 km/h | 17h 51m | 18h 16m |
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 Sepang to New York?
A non-stop flight from Sepang (KUL) to New York (JFK) takes about 19h 16m. The great-circle distance is 15,169 km (9,426 miles, 8,191 nautical miles), flying north on an initial bearing of 355°.
How far is Sepang from New York?
15,169 kilometres in a straight line over the earth's surface — 9,426 miles or 8,191 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 JFK?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,169 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 19h 16m 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.
