 In terms of air connectivity, Kuala Lumpur is served by two airports. The main airport, Kuala Lumpur International Airport (KLIA) at Sepang, Selangor, which is also the aviation hub of Malaysia, is located about 50 kilometres (31 mi) south of city. The other airport is Sultan Abdul Aziz Shah Airport, also known as Subang Skypark and served as the main international gateway to Kuala Lumpur from 1965 until KLIA opened in 1998. KLIA connects the city with direct flights to destinations in six continents around the world, and is the main hub for the national carrier, Malaysia Airlines and low-cost carrier, AirAsia. KLIA can be reached using the KLIA Ekspres a airport rail link service from KL Sentral, which takes twenty-eight minutes, while travelling by car or bus via highway will take about an hour. Air Asia and other low-cost carrier flights do not fly out of KLIA main terminal but from KLIA2 which is two kilometres from KLIA. KLIA2 is served by an extension of the KLIA Ekspres and by buses from KL Sentral. As of 2007, Sultan Abdul Aziz Shah Airport is only used for chartered and turboprop flights by airlines such as Firefly and Berjaya Air.
