Sultan Hasanuddin International Airport — Makassar, Indonesia

Sultan Hasanuddin International Airport, carrying the code UPG, stands as the main aviation gateway to Sulawesi and much of eastern Indonesia, serving the port city of Makassar on the island's southwestern coast. Named for a seventeenth-century ruler of the Gowa Sultanate who resisted Dutch colonial expansion, the airport reflects the region's proud local history. It replaced an older facility and now handles a large share of eastern Indonesia's air traffic, linking Makassar to Jakarta, Bali, and cities across Kalimantan, Maluku, and Papua. Garuda Indonesia, Lion Air, and other domestic carriers operate frequent flights through its terminals, and the airport also supports connections to nearby regional destinations. As Sulawesi's economy has grown around trade, fishing, and nickel processing, UPG has become an increasingly important logistics and passenger hub, easing the historical isolation of Indonesia's outer islands from the capital.
