Louisville

Louisville Muhammad Ali International Airport – also known by its former official names as Standiford Field and Louisville International Airport – is a civil-military airport in Louisville, Kentucky. The airport was renamed after boxer and Louisville native Muhammad Ali in 2019, three years after his death. The airport covers 1,500 acres (610 ha) and has three runways. Its IATA airport code, SDF, is based on the airport's former name, Standiford Field. Despite being called an international airport, it has no regularly scheduled international passenger flights, but is a port of entry, handling many UPS Airlines international cargo flights through the United Parcel Service's worldwide air hub, often referred to as UPS Worldport.
