Sultan Syarif Kasim II International Airport / Roesmin Nurjadin AFB — Pekanbaru, Indonesia

PKU designates Sultan Syarif Kasim II International Airport, also known as Roesmin Nurjadin Air Force Base, serving Pekanbaru, the capital of Riau province in Sumatra, Indonesia. Despite the military-linked name, it functions as a full civilian international airport handling domestic routes across Indonesia and select international connections to Malaysia and Singapore, reflecting Pekanbaru's role as a hub for the palm oil and petroleum industries. The airport shares infrastructure with Indonesian Air Force operations, a common arrangement at several Indonesian airports. PKU has undergone terminal expansions to accommodate growing business travel tied to the region's oil, gas, and plantation economy.
