Indianapolis Municipal Airport opened on September 24, 1931, replacing the older Stout Field as the primary city airport. The airport was initially built on about 320 acres (130 ha) of land in the southwestern edge of the city, with an additional 627 acres (254 ha) reserved for future expansions at the airport. In 1944, it was renamed Weir Cook Municipal Airport, after US Army Air Forces Col. Harvey Weir Cook of Wilkinson, Indiana, who had become a flying ace during World War I with seven victories and had died flying a P-39 over New Caledonia in World War II. Indianapolis was one of many stops along the first transcontinental air/rail service between Los Angeles and New York that was started by Transcontinental Air Transport (TAT) in 1929. TAT would later become Trans World Airlines (TWA) and continued to serve IND until their merger into American Airlines in 2001. Since 1962, the airport has been owned and operated by the Indianapolis Airport Authority (IAA). The IAA has an eight-member board with members appointed by the mayor of Indianapolis and other officials from Marion, Hendricks, and Hamilton counties in central Indiana. In 1976, the board renamed the airport Indianapolis International Airport. From 1957 to 2008, the passenger terminal was on the east side of the airfield off High School Road. This now-demolished facility was renovated and expanded many times, notably in 1968 (Concourses A and B), 1972 (Concourse D), and 1987 (Concourse C and the attached parking garage). This complex, along with the International Arrivals Terminal (opened in 1976) on the north side of the airfield (off Pierson Drive), was replaced by the Col. H. Weir Cook Terminal on November 12, 2008. The April 1957 Official Airline Guide (OAG) shows 82 weekday departures: 24 Eastern, 22 TWA, 15 Delta, 11 American, 9 Lake Central and 1 Ozark. Eastern had a nonstop to Atlanta and one to Birmingham and TWA had two to New York-LaGuardia; no other nonstops reached beyond Chicago, St. Louis, Memphis, Louisville and Pittsburgh. The first jets were TWA Convair 880s in 1961. Westward nonstops did not reach beyond St. Louis until 1967 when TWA started a JFK-IND-LAX flight with a Boeing 707. In the mid-1970s, TWA ran a widebody Lockheed L-1011 on the nonstop flight to Los Angeles. During the late 1980s and early 1990s, USAir (later US Airways) had a secondary hub in Indianapolis with non-stop jets to the West Coast, East Coast, and Florida and turboprop flights to cities around the Midwest. USAir peaked at 146 daily departures (including its prop affiliates), with 49% of all seats. USAir ended the hub in the late 1990s. FedEx Express began its hub at the airport in 1988, with an expansion of the hub occurring ten years later. The hub employs around 4,000 people and has a sort capacity of nearly 100,000 packages per hour, making Indianapolis the largest FedEx hub in the world outside of the company's SuperHub in Memphis. In the late 1990s and early 2000s, Indianapolis was a hub for then locally based ATA Airlines and its regional affiliate, Chicago Express/ATA Connection. After that airline entered Chapter 11 bankruptcy protection in late 2004, operations at IND were cut, then eliminated in 2006. ATA's demise gave Northwest Airlines an opportunity to expand operations, making Indianapolis a focus city with mainline flights to the West Coast, East Coast, and the South. Northwest was later acquired by Delta Air Lines in 2008, and a decade later, Delta began service from Indianapolis to Paris in May 2018. This flight was the first ever non-stop transatlantic passenger flight out of Indianapolis. The flight, DL500, was suspended in March 2020 due to the COVID-19 pandemic. In 1990, Air Canada began nonstop service from Indianapolis to Toronto Pearson International Airport, marking the first regularly scheduled international flight out of IND.
