Kai Tak Airport (IATA: HKG, ICAO: VHHH) was the international airport of Hong Kong from 1925 until 1998. It was officially known as Hong Kong International Airport from 1954 to 6 July 1998, when it was closed and replaced by the new Hong Kong International Airport at Chek Lap Kok, 30 kilometres (19 mi) to the west. It is often known as Hong Kong Kai Tak International Airport, or simply Kai Tak, to distinguish it from its successor which is often referred to as Chek Lap Kok Airport.
