Movement is afoot at Kuala Lumpur’s second airport, now known as Sultan Abdul Aziz Shah Airport (SZB) and formerly Subang International Airport, which was once Malaysia’s primary international air gateway. The airport served as the main international airport from 1965 until 1995, when the new Kuala Lumpur International Airport (KUL) opened in Sepang, around 28 miles from the center of Kuala Lumpur (KL).
