## Economy

Due to their close proximity, the governments of Bay County and the cities of Midland and Saginaw agreed to own and share a centrally located airport through a special municipal body. The airport's name is an initialism formed from the names of the three owning communities: Midland, Bay County & Saginaw. MBS International Airport, located in Freeland, Michigan was formerly known as Tri-City Airport but was renamed to MBS International Airport in 1994 to prevent confusion with other airports named "Tri-City Airport”.
