Southern Illinois Airport

What Southern Illinois Airport does

Southern Illinois Airport (MDH) is a Class D regional airport located 3nm east of Murphysboro, Illinois, established in 1946 and operated as a public facility by the Southern Illinois Airport Authority. The airport provides aviation infrastructure including runway access, an FAA-certified air traffic control tower (operating 0700-2100 daily), and serves as a base for general aviation, flight training, military operations, and air medical transport in the Southern Illinois region. The airport generates revenue through three primary streams: fuel sales (100LL and Jet A) via its Flightline FBO with both full-service and self-serve options, monthly hangar rentals for based aircraft, and event venue rental of its WWII-era themed Hangar One. The on-site tenant ecosystem spans aviation services (Flightline FBO, Crucial MRO, Code 1 Aviation, Midwest ATC), education (Southern Illinois University Aviation Program), military (Illinois National Guard), medical transport (Arch Air Medical Services, Southern Illinois Health, Dr. Gar Kenny AME), and consumer amenities (St. Nicholas Brewing Company, Yates Awning). The business model combines transaction-based fuel sales, recurring hangar subscriptions, and venue rental fees, with go-to-market executed through direct on-site engagement, social media (Facebook, Instagram, LinkedIn), an events calendar, and a dedicated communications function staffed by a Manager of Communication.
