Soekarno Hatta International Airport - Most Important Airport in Indonesia Situated in Benda Tangerang, it is the most important airport in Indonesia. Started out in 1985 while handling only domestic traffic, it is now regarded as the busiest airport in Southeast Asia by the Airports International Council.
Two airports in Jakarta: CGK (Cengkareng airport) and HLP (Halim Perdana Kusuma). Most of domestic and international flights are in CGK and only a handful of domestic flights by Citilink are in HLP. So obviously CGK is the place that you should book. .
