The birth of Delta Air Lines began with the founding of a small aerial crop dusting company in Macon, Georgia called Huff Daland Dusters in 1924. The company expanded to become an international mail carrier in 1927. In 1928, co-founder C.E. Woolman renamed the company Delta Air Service.
The Mississippi Delta area, the central point of most of the company's operations, inspired the change of name. In 1929, Delta Air Service began offering passenger flights. The company expanded in the 1930s and 1940s, during which time passenger flights became the primary operations of the company. The company first began using the name Delta Air Lines in the 1930s and officially became Delta Air Lines, Inc. in the 1940s.
