[email protected] Abstract: Japan International Cooperation Agency in 2012 has conducted a research regarding multi-airport systems in Greater Jakarta which stated that a new airport should be operating in this metropolitan area by 2019 to accommodate future demand. According to the 2012 study, no airports except Soekarno-Hatta Airport were able to handle commercial flights in the city due to regulatory and environmental issues. However, this is not the case. Halim Perdanakusuma Airport, now a secondary airport, has been operating commercially since 2014 and another secondary airport, Pondok Cabe Airport, has the potential to be operational in the future. New air demand forecasts and air traffic distributions with different scenarios have been produced and analysed to reflect current situation in Greater Jakarta. The result of these analyses differs from the Japan International Cooperation Agency study and shows that the operation of the new airport can now be postponed until 2022 at the earliest. Keywords: Market Analysis, Demand Growth Drivers, Traffic Forecast, Sensitivity Analysis, Air Traffic Distributions 1. INTRODUCTION From 2010 to 2012, the Japan International Cooperation Agency (JICA) conducted a master plan study on multiple-airport development for Greater Jakarta Metropolitan Area (GJMA). The background of the JICA study was the overcapacity experienced by the existing terminals in Soekarno-Hatta Airport (CGK).
