Boeing debuted the 737 in January 1967, with stewardesses in miniskirts from no-frills PSA, Pacific Southwest Airlines, lined up along the wing. The San Diego–based carrier’s business model helped inspire a Texas lawyer named Herb Kelleher to start Southwest Airlines at Love Field in Dallas that same year. Competing on short-hop flights within California and Texas, the airlines were beyond the reach of the all-powerful federal Civil Aeronautics Board that determined interstate fares and routes.
