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 and costs 55 Malaysian Ringgit (roughly 13.50 US Dollar), while travelling by car or bus via highway will take about an hour but cost a lot less. Direct buses from KLIA to the city centre are plentiful (every 10 to 15 minutes during peak hours), air-conditioned and comfortable with fares ranging from 11 Malaysian Ringgit (roughly 2.70 US Dollar) to 15 Malaysian Ringgit (roughly 3.70 US Dollar). 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 a free shuttle bus service from KLIA. As of 2018, Sultan Abdul Aziz Shah Airport is only used for chartered and turboprop flights by airlines such as Firefly and Malindo Air.Public transport in Kuala Lumpur and the rest of the Klang Valley covers a variety of transport modes such as bus, rail and taxi. Despite efforts to promote usage of public transport, utilisation rates are low as only 16 percent of the population used public transport in 2006. However, public transport utilisation is set to rise with the opening of 2 light metro (LRT) extension lines on 30 June 2016. Rail transport in Kuala Lumpur encompasses the light metro (LRT), monorail, commuter rail and Airport rail link. The LRT system has 2 lines namely, Kelana Jaya Line and Ampang Line, connecting many locations in the city with major suburbs in Greater Kuala Lumpur. The Monorail serves various key locations in the city centre whereas the KTM Komuter runs between the city and the suburbs. The main rapid transit hub is KL Sentral, which is an interchange station for the rail systems. KL Sentral is also a hub for intercity railway service namely KTM Intercity and KTM ETS. It provides rail services to as far as Singapore in the south, and Hat Yai, Thailand, in the north. The rail system in Kuala Lumpur is expanding fast with more train lines due for completion or in the pipeline. In December 2016, the 1st phase of Klang Valley Mass Rapid Transit (MRT) Project, Sungai Buloh-Kajang Line was completed, the remaining phases of the line has been open in July 2017.The largest public transport operator in Kuala Lumpur and the Klang Valley is Prasarana Malaysia via its subsidiaries of Rapid Rail and Rapid Bus using Rapid KL brands service. Since the take over from Intrakota Komposit Sdn Bhd, Prasarana Malaysia has redrawn the entire bus network of Kuala Lumpur and Klang Valley metropolitan area to increase passenger numbers and improve Kuala Lumpur's public transport system. The Prasarana Malaysia has adopted the hub and spoke system to provide greater connectivity, and cut down the need of more buses.In Kuala Lumpur, most taxis have distinctive white and red liveries.
