Memphis mayor Watkins Overton put together a commission in 1927 to establish an airport. It was built on a 200-acre (81 ha) plot of farmland seven miles (11 km) from downtown Memphis and opened on June 14, 1929, as Memphis Municipal Airport. The two-day dedication ceremony featured aerial stunts and the arrival of over 200 aircraft. In its early years the airport had three hangars and a sod runway. Standard Oil of Louisiana built the terminal after securing the right to supply all of the airfield's oil and gasoline. In 1930, runway lights were installed after an aircraft landed in the Mississippi River because it could not find the airport at night. Robertson Aircraft Corporation, which would merge into American Airways, started passenger flights to New Orleans and St. Louis in April 1930 on Ryan monoplanes. The following June, American Airways commenced the first airmail service from Memphis. Chicago and Southern Air Lines was headquartered in the city from 1934 to 1935 and from 1941 to 1953, when it was acquired by Delta Air Lines. During the 1930s, Memphis figured on American's east–west route between New York and Los Angeles and on Chicago and Southern's north–south route linking Chicago to New Orleans. The Works Progress Administration helped construct a new terminal building, which was inaugurated in October 1938. It had three stories and an Art Deco design. That year 31,000 passengers used the airport.

After the United States entered World War II, the city government leased the airfield to the War Department in July 1942. That December the headquarters of the 4th Ferrying Group of the Army Air Forces Air Transport Command shifted to the airport. The group was tasked with sending new aircraft overseas; pilots departed Memphis for South America and then flew over the South Atlantic Ocean to Africa. Personnel such as mechanics and engineers underwent training at the base and then traveled overseas. Chicago and Southern's repair facilities at the airport were used to repair military planes. Commercial air service continued, though it was limited. The ferrying group's postwar activities included moving planes off deactivated bases. For a period in 1946, Memphis served as headquarters for the Continental Division of the Air Transport Command, which oversaw the 4th Ferrying Group and ran scheduled flights for military personnel throughout the country. The ferrying group ceased operations in March 1947. City officials reached an agreement with the federal government in January 1949 to regain control of the airfield.

Five trunk carriers flew to Memphis as of 1947, and two years later, a regional airline named Southern Airways launched operations with multi-stop service to Atlanta. The airport opened the first air-cargo terminal in the country in February 1958. The following year, passenger counts crossed one million. In August 1960, the city received its first scheduled jet flight; Delta Air Lines started using Convair 880s on its Chicago–Memphis–New Orleans route. The United States Supreme Court in Turner v. City of Memphis ordered the desegregation of the airport in 1962. Jesse Turner, an African-American banker and civil rights activist, had filed the case after he was denied service in the main dining room of the restaurant.

In June 1963, a new terminal built for the jet age was dedicated, and the airport was rechristened Memphis Metropolitan Airport. United Nations ambassador Adlai Stevenson II spoke at the inauguration ceremony and replaced the ribbon cutting with a rocket launch. The terminal was designed by the local firm Mann & Harrover and became Roy Harrover's most famous work. It was one of the first airport terminals to have a two-level design where passengers boarded aircraft via jet bridges on the upper level and collected their luggage on the lower level. Another unique aspect of the structure was its columns resembling martini glasses. It opened to passengers in July and was part of an expansion project that also included a control tower and a north–south runway.

In 1969, the Memphis–Shelby County Airport Authority was formed, and the facility changed its name to Memphis International Airport after being designated a customs port of origin. Expansion continued in the 1970s. A west concourse was added in 1974 and an east one the following year. The airport constructed another north–south runway, a parking garage, and a road linking the terminal to Interstate 240. The central concourse was extended as well. In 1988, the latter concourse was named B, the west one A, and the east one C.

Hub status

Air-cargo company Federal Express moved its base to Memphis from Little Rock, Arkansas, in 1973. Memphis was selected because of its temperate climate and location in the middle of the country. The decision was credited with enabling the city to go from a river port of decreasing economic relevance to an important global distribution center. Shipments flew into and out of the hub overnight on aircraft that exclusively carried cargo.
