The first scheduled airline flight in Tennessee took place in Chattanooga in 1928 at Marr Field, dedicated in December 1919, named for Walter L. Marr, off present-day Amnicola Highway. Chattanooga was a stopover on the Contract Air Mail route served by Interstate Airlines between Atlanta and Chicago. Charles Lindbergh, the world-famous aviator who had piloted the Spirit of St. Louis over the Atlantic Ocean in May 1927, flew into Marr Field on October 5, 1927. In 1930, due to the interest and foresight of John Lovell, president of the local Kiwanis Club and American Red Cross, a new Chattanooga Airport opened with an unpaved runway at its present location and was named Lovell Field in his honor. In 1936, the landing area was expanded and runways paved as a part of the New Deal's Works Progress Administration (WPA). The original terminal building was built at that time. During World War II, Lovell Field was a military training facility. Growth in aviation in the 1950s led to a transfer of airport operations to the City of Chattanooga and airport expansion with a new runway, the primary runway today. The original terminal building, dating from the 1930s, was expanded in 1950 and 1955 by the city before being replaced by a new terminal in 1964. The airport's ownership was transferred from Chattanooga to the Chattanooga Metropolitan Airport Authority (CMAA) in July 1985. The current passenger terminal, designed by Gensler, opened in 1992. In 2011, a 1 megawatt solar farm located on the southwest corner of the airfield was constructed. An additional 1.1 megawatts were added to the solar farm in the summer of 2013. By 2017, the farm was providing approximately 90% of the airport's electricity. Chattanooga Metropolitan Airport was home to the 241st Engineering Installation Squadron (241 EIS) of the Tennessee Air National Guard until late 2010, when the squadron moved to a Bonny Oaks facility near the airport.
