Juanda International Airport — Surabaya, Indonesia

Surabaya's airport carries the name of Juanda Kartawidjaja, a former Indonesian prime minister, and SUB now serves as the primary gateway to the country's second-largest city and the historic capital of East Java. The airport originated as a joint civil-military facility, and the Indonesian Navy still maintains a presence alongside commercial operations at the site. Surabaya's role as an industrial and shipping center along the Java Sea makes the airport a critical link for domestic cargo and business travel, complementing the port traffic that has defined the city for centuries. Budget carriers, particularly Lion Air, which was founded in the country and built out extensive domestic networks, use Juanda as a major operating base. Passenger numbers have grown substantially since a modern second terminal opened, easing congestion from the older facility. Surrounding East Java offers travelers access to Mount Bromo and other volcanic landscapes not far beyond the city itself.
