Sepang to Phuket

1h 18mgate to gate

The flight from Kuala Lumpur International Airport (KUL) to Phuket International Airport (HKT) covers 705 km (438 miles) and takes approximately 1h 18m gate to gate for a typical jet.

The route heads north-west on an initial great-circle bearing of 328°, passing near 5.4° N, 100.0° E at its midpoint.

How this is worked out

  1. Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
  2. Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 705 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 53m.
  4. Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 1h 18m gate to gate.
  5. Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
705 km / 805 km/h = 53m airborne
            + 25 min ground = 1h 18m 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.

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 Phuket?

A non-stop flight from Sepang (KUL) to Phuket (HKT) takes about 1h 18m. The great-circle distance is 705 km (438 miles, 381 nautical miles), flying north-west on an initial bearing of 328°.

How far is Sepang from Phuket?

705 kilometres in a straight line over the earth's surface — 438 miles or 381 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 HKT?

This page calculates the direct-line time and distance; it does not track airline schedules. At 705 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.

Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
