City Airport began on July 17, 1928, via Transamerican Airlines. That day pilot C.V. Pickup departed with five sacks of mail en route to New York City. Lansing postmaster Walter G. Rogers was among those present to witness the event. In 1929, J.D. Foster completed construction on a 60-by-120-foot, aircraft hangar, the first building in what would become known as the Francis Aviation Complex at Capital City Airport. By the end of the year, fixed-base operators Foster Airways, SKF Air Service, Inc., and Wolverine Flying Service, Ltd. had constructed hangars at the airport. Passenger service commenced on September 1, 1929, by Kohler Aviation Corp. to Detroit and Milwaukee. By 1934, Pennsylvania Airlines and Transport was providing air mail and passenger service to Detroit, Grand Rapids, Muskegon, and across Lake Michigan. The Foster Hangar housed a flight school operated by Harvey Hughes from 1934 to 1936. In the late 1930s, Lansing aviator Lt Arthur J. Davis operated Michigan Airways, Inc. out of the hangar. During World War II, Francis Aviation and Hughes Flying Service provided ground and flight training to 300 pilots per month as part of the U.S. Government's Civilian Pilot Training Program and War Training Service. The training included three weeks of instruction at Michigan State College and continued at Capital City Airport. In 1940, the original terminal building, a 100-by-100-foot concrete hangar, and an adjoining office wing at the west end of the airport were built. The airport acquired next to the north side of the airport, and runway 06/24 was extended by . Pennsylvania Central Airlines began Douglas DC-3 service on June 5, 1940. The same year, the airport unsuccessfully bid for an $8.4 million Aircraft Engine Research Laboratory of the National Advisory Committee for Aeronautics. 1950s–1970s Demand for air service led to the building of the current terminal building in 1959. The terminal has had several renovations and additions since then. In April 1967, a new $38,000 observation room opened, where viewers can hear radio communications between pilots and the control tower through a loud speaker. In the early 1960s, Lansing Community College leased the Francis Aviation Complex at Capital City Airport. The college moved to a new facility near the airport terminal in 1974. In March 1960, Francis Aviation Co. built two circular (roundtable) airport hangars costing $400,000 at the airport, believed to be the world's first. In 1963, Capital City Airport served over 100,000
