Owned and operated by the St. Louis County Government, Spirit is unique in that airport funding does not come from general revenue tax dollars, but from revenue generated from wholesale fuel sales, land development, and real estate rental. With an annual economic impact of $400 million on the surrounding community, Spirit continues to be a self-supporting and profitable airport. By re-investing profits back into its operations, Spirit of St. Louis Airport has continued to improve its facilities and promote the growth of aviation in the St. Louis region, as well as non-aviation businesses in the surrounding community.
