Delta Air Lines traces its origins to 1924, when Huff Daland Dusters was established in Macon, Georgia, as a crop dusting service. In 1928, C.E. Woolman and a group of investors purchased the company and renamed it Delta Air Service, after the Mississippi Delta region where it operated. The airline began passenger service in 1929, operating a route between Dallas, Texas, and Jackson, Mississippi.
Delta grew steadily through the 1930s and 1940s, expanding its route network across the southeastern United States. The airline was incorporated as Delta Air Lines in 1945 and became a publicly traded company. Delta was among the first airlines to operate the Douglas DC-3, which became the workhorse of commercial aviation in the late 1930s and 1940s.
In the 1950s and 1960s, Delta expanded nationally and internationally, introducing jet service in 1959 with the Douglas DC-8. The airline merged with Chicago and Southern Air Lines in 1953 and Northeast Airlines in 1972, significantly expanding its route network. Delta became one of the major U.S. trunk carriers, competing with American, United, and Eastern Airlines.
Delta acquired Western Airlines in 1987, adding routes in the western United States and expanding its presence in the Pacific. The acquisition made Delta one of the largest U.S. airlines and established its position as a truly national carrier.
The airline industry faced severe disruption following the September 11, 2001 terrorist attacks, which caused a dramatic decline in air travel demand. Delta, like most major U.S. airlines, struggled financially in the years following the attacks. The airline filed for Chapter 11 bankruptcy protection in September 2005, citing high fuel costs, labor costs, and competition from low-cost carriers.
Delta emerged from bankruptcy in April 2007 with a restructured balance sheet and lower cost structure. Shortly after emerging from bankruptcy, Delta announced a merger with Northwest Airlines, which was completed in October 2008. The Delta-Northwest merger created the world's largest airline at the time, combining Delta's strengths in the southeastern United States and transatlantic routes with Northwest's strengths in the upper Midwest and transpacific routes.
Richard Anderson served as CEO from 2007 to 2016, leading the airline through its bankruptcy emergence, the Northwest merger, and a period of strong profitability. Ed Bastian became CEO in May 2016 and has continued Delta's focus on premium service, operational reliability, and financial discipline.
Delta has made strategic investments in airline partners to strengthen its global network. The company holds a 49% stake in Virgin Atlantic, a significant stake in LATAM Airlines Group (South America's largest airline), and a stake in Aeromexico. These investments provide Delta with preferred partner relationships and revenue sharing on key international routes.
In FY2024, Delta reported record full-year revenue and approximately $5 billion in pre-tax income, reflecting strong travel demand and the airline's premium positioning.
