Aeroflot Lupinissia (literally, "Lupinissia Air Fleet") is Kelssek's fourth-largest airline by passenger numbers and the largest by fleet size. It operates an extensive cargo network in addition to its passenger operations. A state enterprise of the Lupinissia provincial government, its corporate headquarters are in Ulyanov.
Aeroflot Lupinissia's route network is particularly strong in western Kelssek with some international flights mostly operated from Ulyanov. Its aircraft feature a wolf's head on the tail and are painted reddish brown with dark green cheatlines. While maintenance standards have improved in recent years to a generally good level, the colour scheme and the state of repair their aircraft were reputedly in led it to be nicknamed "Rust Air" in the 1970s and 80s. Remarkably, in spite of (or, perhaps, because of) being notorious for frequent delays for maintenance reasons, the airline has never had a fatal accident.
