It wasn't until 1947 that the airfield was transferred to the Louisville Air Board where it was used for commercial operations. In 1970, the airport terminal was expanded, including the main lobby and a brand-new Delta Air Lines concourse measuring 33-000-square-foot. In the 1980s, a new plan was devised to build a new terminal, with a proposed capacity for nearly 2 million passengers. This new terminal was opened in the 1990s, with new runways and a new name of Louisville International Airport. In 2019, the airport was renamed to Louisville Muhammad Ali International Airport, after a vote by the airport authority to rename it after the Louisville native boxing legend.
