Hang Nadim Airport (IATA: BTH, ICAO: WIDD), also known as Hang Nadim International Airport, is located in Batam, Riau Islands (part of Sumatra), Indonesia. It is the only airport on the island.
It has been the primary method of transport to and from Batam, alongside ferries to neighboring islands (including Singapore). As Batam continues to develop its tourism sectors, the Hang Nadim has proved a sufficiently effective airport. Originally developed as an alternative airport for Singapore Changi Airport in mind (should in case an emergency for aircraft force a redirect), the Hang Nadim has facilities and the longest runway in Indonesia, sufficient for Boeing 747s and several times more passengers than it is currently serving. However Changi was developed to grow, and the Sijori Growth Triangle region has 5 airports, including Senai International Airport in Johor Bahru, Raja Haji Fisabilillah International Airport in Tanjung Pinang, Bintan Island and the Seletar Airport.
