Mushaf Air Base — Sargodha, Pakistan

SGI is the IATA code assigned to Mushaf Air Base, located near Sargodha in Punjab, Pakistan. Unlike most airports catalogued under IATA codes, Mushaf is a military installation operated by the Pakistan Air Force and has no scheduled commercial passenger service. Historically known as Sargodha Air Base, it has served as a frontline PAF installation with a significant role in the country's air defense history, including operations during past regional conflicts. The base hosts fighter squadrons and associated training and maintenance infrastructure. Because SGI functions purely as military infrastructure, travelers will not find ticketed flights, terminals, or civilian ground transport connections associated with this code, and it does not appear in standard airline booking systems.
