History of Delta Air Lines: From Crop Dusting to Global Leader
The Early Years (1925-1945)
Huff Daland Dusters Era
Delta’s story begins in 1925 as Huff Daland Dusters, the world’s first aerial crop-dusting operation. Based in Macon, Georgia, the company protected cotton crops from boll weevils and other pests.
Birth of Delta Air Service
In 1928, C.E. Woolman led an ownership change, renaming the company Delta Air Service after the Mississippi Delta region. Passenger service launched in June 1929, connecting Dallas, Shreveport, Monroe, and Jackson.
Becoming Delta Air Lines
After securing a U.S. airmail contract in 1934, rapid growth followed. The company officially became Delta Air Lines in 1945.
Expansion and Major Milestones (1946-2000)
Jet Age Transformation
Key developments shaped Delta’s growth:
- 1946: Regular freight services begin
- 1949: First discounted airfares introduced
- 1953: Acquisition of Chicago and Southern Air Lines
- 1959-1965: First U.S. airline with multiple jet aircraft types
- 1970: Complete transition to jet-powered fleet
Strategic Acquisitions

Financial Restructuring (2005-2007)
Rising fuel costs forced Delta into Chapter 11 bankruptcy in 2005. The airline successfully restructured and emerged stronger in 2007, blocking a US Airways takeover attempt.
Northwest Airlines Merger (2008-2010)
The 2008 merger with Northwest Airlines created one of the world’s largest airline networks. By 2010, full integration was complete, expanding Delta’s Airbus fleet and international reach significantly.
