Indonesia is planning to begin construction on a new international airport in Karawang, West Java, in 2015.
The project will support Soekarno-Hatta International Airport, the country's existing gateway, and includes the construction of four runways and two terminals.
The new Karawang International airport, with a passenger handling capacity of 70 million passengers every year, will be built on a 900ha site and is expected to begin operations in 2019.
Indonesia Ministry of Transportation air transportation director Herry Bhakti Gumay told the Jakarta Post that the country needs the new airport badly because passenger numbers through Soekarno-Hatta International Airport have reached more than 50 million a year.
"The construction of this airport will be conducted in phases until it reaches its ultimate capacity after 2019," Gumay said.
"We are going to construct the airport through a public-private partnership scheme."
Following the first phase of construction, which is expected to cost IDR10 trillion ($1.09bn), the airport will be able to handle 20 million passengers each year.
The construction, which is not part of the Master Plan for the Acceleration and Expansion of Indonesian Economic Development (MP3EI) programme, will be speeded up by the Indonesian government to help reduce the load at Soekarno-Hatta.
Soekarno-Hatta airport's passenger handling capacity reached 51.1 million in 2011, while the airport's total capacity was to accommodate only 22 million passengers.
Under the MP3EI programme, the Indonesian government has allocated IDR32 trillion ($3.48bn) for the construction and expansion of 14 airports in the country.
The country has also built the Kuala Namu International Airport in Medan, North Sumatra, which is expected to begin operations in 2013, and work on Kertajati International Airport in Majalengka, West Java, is set to begin soon.
The Kertajati airport project, expected to cost IDR8.29 trillion ($903.61m), will be performed by state-owned airport operator Angkasa Pura I, and the company is soon expected to sign a Memorandum of Understanding (MoU) with the West Java provincial government.
Its construction, involving investments from China and India, will begin in 2014, and support Husein Sastranegara Airport, as the latter airport cannot be further expanded due to its location in the centre of Bandung.
The airport is expected to accommodate 20 million passengers each year in its first phase of construction, and will have the capacity for 70 million, which is the same as the new airport in Karawang, upon completion.
