Delta Air Lines
Delta Air Lines started as a crop dusting company — Huff Daland Dusters — in Macon, Georgia on May 30, 1924. It’s claimed that Huff Daland Dusters was one of the world’s first commercial crop dusting operations.
A year later it moved to Monroe, Louisiana, and in 1928 it was bought out by one of the company’s founders, Collett Woolman, who renamed the company Delta Air Service, and began refocussing the company on passenger services, and the lucrative air mail routes being handed out by the US government.
The company’s name refers to the Mississippi delta, where the company was then headquartered. It has since moved back to Georgia, and is now one of the USA and the world’s largest airlines.
