It is located in Seletar in the north-eastern area of the main island, and is managed by the Changi Airport Group. There has been a proposal to extend its runway to 2,000 metres, so as to be able to receive the Boeing 737 used by many budget airlines. However, after considerations by the Singapore Government and the CAAS, they decided to build a Budget Terminal in Singapore Changi Airport instead.
