As Batam continues to develop its tourism sector, Hang Nadim has proved to be a sufficiently effective airport. Originally developed as an alternative for Singapore Changi Airport (should an emergency force a redirect for aircraft), Hang Nadim has facilities sufficient for Boeing 747s and A380s, including the longest runway in Indonesia. It can also serve several times more passengers than it is currently serving.Lion Air has based itself from this airport and build a maintenance facility, as Jakarta's Soekarno–Hatta International Airport is severely congested. BP Batam is planning to build a new terminal. Terminal 1 (old building) and Terminal 2 (new building) BP Batam is going to renovate the terminal building, from about 35.000 m2 (4-6 aerobridges) to 88.000 m2 (12 aerobridges). A new runway is also planned by BP Batam. Later on 2016, BP Batam is going to build a monorail from Hang Nadim Airport to Batu Ampar.
