Kuala Lumpur International Airport (KUL) serves Kuala Lumpur, Malaysia, sitting at an elevation of 64 feet and located about 28 miles from the city center. The airport's low elevation places it close to sea level, a relevant factor for takeoff and landing performance calculations, though it has minimal bearing on turbulence encountered en route.

Traffic through Kuala Lumpur International Airport reflects its role as a major hub connecting Southeast Asia with the wider Asia-Pacific region, East Asia, and long-haul destinations in Europe. The mix of routes points to a strong international character, linking Malaysia with other parts of Southeast Asia as well as more distant markets across Asia and beyond. This breadth suggests a flight profile that spans both shorter regional hops and extended intercontinental journeys, meaning travelers departing or arriving here may experience varying atmospheric conditions depending on the length and direction of their route.

Given its position in the region, flights to and from Kuala Lumpur International Airport often cross a mix of tropical and subtropical air masses, particularly on routes toward East Asia and Australia. Those flying longer sectors toward Europe will traverse a wider range of climatic zones. The airport's scale and connectivity make it a significant gateway for both regional and long-haul air travel in Southeast Asia.
