Hang Nadim International Airport — Batam, Indonesia

Hang Nadim International Airport serves Batam, an Indonesian island close to Singapore that has become a major manufacturing and free-trade zone across the strait. The airport, coded BTH, sits at 126 feet, and a single runway carries a substantial volume of traffic thanks to Batam's role as a budget-friendly alternative to Singapore for both business and leisure travelers. Many visitors combine a short ferry ride from Singapore with a flight through BTH to reach other parts of Indonesia more cheaply than connecting through Singapore's own airport. Its name honors Hang Nadim, a legendary warrior figure from Malay history associated with the wider Riau Islands region. Domestic routes from BTH connect Batam to Jakarta and other major Indonesian cities, supporting the island's dense manufacturing and shipping economy, and cargo traffic tied to electronics assembly plants on the island adds further weight to the airport's role in regional trade. Ferry terminals sit only a short taxi ride from the passenger hall.
