Nashville's first airport was Hampton Field, which operated until 1921. It was replaced by Blackwood Field in the Hermitage community, which operated between 1921 and 1928. The first airlines to serve Nashville, American Airlines and Eastern Air Lines, flew out of Sky Harbor Airport in nearby Rutherford County. By 1935, the need for an airport larger and closer to the city than Sky Harbor Airport was realized and a citizens' committee was organized by mayor Hilary Ewing Howse to choose a location. A 340-acre (1.4 km2) plot along Dixie Parkway (now Murfreesboro Pike) composed of four farms was selected, and construction began in 1936 as one of the first major Works Progress Administration projects in the area. The airport was dedicated on November 1, 1936 as Berry Field, named after Col. Harry S. Berry, the Tennessee administrator for the Works Progress Administration. It opened in June 1937 with much fanfare, including parades, an air show and an aerial bombardment display by the 105th Aero Squadron, which was based at the field. Passenger service began in mid-July through American Airlines and Eastern Airlines, both of which operated Douglas DC-3s. The new airport had three asphalt runways, a three-story passenger terminal, a control tower, two hangars and a beacon, and was built at a cost of $1.2 million. In its first year, Berry Field served 189,000 passengers. During World War II, the airfield was requisitioned by the United States Army Air Forces Air Transport Command as the headquarters for the 4th Ferrying Command for movement of new aircraft overseas. During this time, the federal government expanded the airport to 1,500 acres (6.1 km2). At the end of the war, the airport was returned to the control of the city, with a number of facilities remaining for support of the tenant unit of the Tennessee National Guard. The airport had been enlarged by the military during World War II, but in 1958 the city aviation department started planning to expand and modernize the airport. In 1961, a new 145,000 square feet (13,500 m2) terminal opened by Briley Parkway, west of Runway 2L. In that year, the first jets at Berry Field, American Airlines 720/720Bs, began scheduled service, and the six airlines that served Nashville carried 532,790 passengers. These renovations also included expansion of an existing runway, with 2L/20R extended by 600 feet (180 m), and the construction of a new crosswind runway, 13/31. In 1962, Nashville became the first municipal airport in the United States with a public reading room when the Nashville Public Library opened a branch inside the terminal. By the 1970s, the airport was again in need of expansion and modernization. In 1973, the newly created Metropolitan Nashville Airport Authority (MNAA) finalized a plan for the long-term growth of the airport; the plan included a new terminal and a new parallel runway across Donelson Pike to increase capacity by reducing time between takeoffs and landings. In the early 1980s, the MNAA commissioned Robert Lamb Hart, in association with the firm of Gresham, Smith and Partners, to design a modern terminal; construction began on the opposite side of the existing two crossing runways in 1984 and was completed in 1987. The new terminal had three main concourses and a smaller commuter concourse radiating from a distinctive three-story atrium. An international wing was built in Concourse A, and the airport was renamed Nashville International Airport/Berry Field. Although the Berry Field name is rarely used, the airport's IATA code of BNA is short for Berry Field Nashville, and the military facilities at the airport are still commonly known by this name. In 1989, a new parallel runway (2R/20L) was opened for use. American Airlines announced in 1985 that it would establish a hub at Nashville, and it officially opened in 1986.
