Smith Reynolds Airport — Winston Salem, United States

INT is the code for Smith Reynolds Airport, located in Winston-Salem, North Carolina, and named after Smith Reynolds, a member of the R.J. Reynolds tobacco family and an aviation enthusiast who died young in a mysterious shooting. Once a busier commercial airport, INT now primarily serves general aviation, corporate flights, and cargo operations, with most Winston-Salem area passenger traffic having shifted to nearby Piedmont Triad International Airport. INT retains historical significance as one of the earliest municipal airports in the southeastern United States, and it continues to support flight training, charter operations, and business aviation for the Piedmont Triad region's corporate and manufacturing sectors.
