Atlanta-based Delta Air Lines is set to celebrate its 100th anniversary on June 2, 2025. As the world's number one airline in revenue, Delta becomes the first U.S. airline to reach this centennial milestone.

From Crop Dusting to Commercial Flights

Delta Air Lines began in 1925 as a crop-dusting operation called "Huff Daland Dusters" in Macon, Georgia. Over the past century, it has overcome numerous challenges to achieve its current status. Initially plagued by financial difficulties, the company relocated to Louisiana and rebranded as "Delta." The 1930s saw a failed attempt at passenger service, followed by years of losses in the 1980s and 1990s. The company also weathered bankruptcy, hostile takeover attempts, the 9/11 terrorist attacks, and the pandemic. Today, Delta is Atlanta's largest private employer and anticipates its most profitable year in history.

Pioneering Passenger Service and the Hub-and-Spoke Model

Delta entered the passenger transport market in 1929 with the purchase of a 5-seater aircraft. The inaugural route connected Dallas, Louisiana, and Jackson, Mississippi. However, the service was short-lived due to the inability to secure lucrative U.S. mail contracts. Delta returned to crop dusting until 1934 when it successfully bid for another mail contract, marking its resurgence in aviation. As the airline expanded its routes, it relocated its operations and maintenance base to Atlanta, eventually moving its entire headquarters there in 1941.

Delta pioneered the "hub-and-spoke" model centered around Atlanta, transforming Hartsfield-Jackson Atlanta International Airport into the world's busiest airport. Currently, Delta employs approximately 100,000 people and serves over 800 destinations in 190 countries worldwide.

New Routes and Future Prospects

Delta is set to launch a new route to Marrakech, Morocco, in October 2025 and resume its Atlanta-Accra, Ghana, route in December, which was suspended in 2012. The African routes are among Delta's most popular, with 31 weekly direct flights to five African cities.
