Distance and flight time from Seoul to Langkawi
The great-circle distance between Seoul and Langkawi is 4,420 km (2,746 mi, 2,387 nautical miles). By private jet the flight takes between 5h 44m and 12h 32m block time depending on the aircraft class. For most travellers a super-midsize jet fits: it covers the route nonstop in about 6h 10m.
- Light jet: 8h 22m (with one fuel stop)
- Midsize jet: 7h 52m (with one fuel stop)
- Super midsize jet: 6h 10m (nonstop)
- Heavy jet: 6h 03m (nonstop)
- Ultra long range jet: 5h 44m (nonstop)
Empty legs and aircraft on the Seoul – Langkawi route
Over the last 18 months we recorded 3 empty legs from Seoul to Langkawi. The most frequent aircraft were Challenger 350 and 350 8 seats. Most flights operate from Seoul, KR (RKSS) to Langkawi, MY (WMKL).
Range and fuel stops
Not every jet can fly every route nonstop. With reserves, light jets reach about 2,800 km, super midsize jets around 5,500 km and ultra long range jets more than 11,000 km. If the destination is further away, the operator plans a fuel stop of roughly 45 minutes.
For transatlantic flights or routes to Asia the larger class often pays off: it costs more per hour but saves stops and therefore time.
- Turboprop / PC-12: up to approx. 2,200–2,800 km
- Light jet: up to approx. 2,800 km
- Midsize jet: up to approx. 3,700 km
- Super midsize jet: up to approx. 5,500 km
- Heavy jet: up to approx. 7,000 km
- Ultra long range: 11,000 km and more
Calculating the distance between airports
We calculate distance as the great-circle distance (the shortest path over the globe) and also show it in nautical miles, the standard unit in aviation. Because aircraft follow airways and approach procedures, the distance actually flown is slightly longer; the flight time already includes this.
How we calculate
- Distance: great-circle calculation from both airports’ coordinates, plus 5% for airways and approach procedures.
- Flight time: distance flown divided by the class’s typical cruise speed, plus 15 minutes for climb and descent and 10 minutes of taxi per take-off and landing.
- Fuel stops: added once the route exceeds practical range with reserves, 45 minutes on the ground per stop.
- Wind is not included. Strong headwinds (typically westbound across the Atlantic) can add 10–15% to flight time; tailwinds shorten it.
Frequently asked questions
How far is it from Seoul to Langkawi?
The great-circle distance is 4,420 km (2,746 mi) or 2,387 nautical miles. The distance flown is about 5% longer because of airways.
How long is the flight from Seoul to Langkawi?
By private jet about 6h 10m in a super-midsize jet and 5h 44m in the fastest jet (an ultra-long-range jet). A typical airliner flying nonstop takes about 6h 15m gate to gate. Wind and air traffic control can change this by a few minutes.
Can a light jet fly Seoul – Langkawi nonstop?
No, a light jet would need one fuel stop and about 8h 22m in total. Nonstop flights start with a super-midsize jet (6h 10m).
How much is a private jet from Seoul to Langkawi?
A one-way charter in a super-midsize jet costs roughly €53,100 to €100,000 for the whole aircraft. Empty legs on this route recently had a median price of €22,200.
