Built in 1943 as the Estrella Army Air Field, it saw little military activity during the War, but its advent paved the way for the future of aviation in the area. Sherwood Field, a few miles to the south, played a more colorful role in the beginnings of aviation in northern San Luis Obispo County. Pacific Seaboard Air Lines was the first airline to serve Paso Robles. In 1933, Pacific Seaboard was operating two daily round trip flights with single engine Bellanca CH-300 aircraft on an intrastate routing of Los Angeles - Santa Barbara - Santa Maria - San Luis Obispo - Paso Robles - Monterey - Salinas - San Jose - San Francisco. Pacific Seaboard would subsequently move its entire operation to the eastern U.S., be renamed Chicago and Southern Air Lines, become a large domestic and international air carrier and then in 1953 be acquired by and merged into Delta Air Lines thus providing Delta with its first international routes.
