Chicago and Southern Air Lines Apparel
"The Valley Level Route - 900 Miles of Flat Country"
Chicago and Southern actually began operations in California as Pacific Seaboard Air Lines. The small fleet of Bellanca flew up and down the Pacific coastline between Los Angeles and San Francisco, making seven stops along the way.
The owner of the company, Carleton Putnam, decided to move the company back east after winning the contract to carry mail along Air Mail Route 8. In 1935, they changed to name of the airline to Chicago & Southern. Over the years, the fleet was grown to include D-3s, DC-4s, Constellations, and in 1953 the airline was merged with Delta Air Lines, greatly expanding Delta’s reach.
