Grounded: Pacific Southwest Airlines

Pacific Southwest Airlines (PSA) established itself as a distinct operator focused on offering discounted fares, effectively creating a market segment that would later be adopted by Southwest Airlines. Prior to its struggles, PSA functioned as an influential prototype demonstrating successful low-cost airline operations within the United States. Following deregulation in the late 1970s, PSA experienced significant difficulties navigating increased competition and evolving industry dynamics. Financial challenges mounted for the carrier throughout the early 1980s, leading to operational setbacks and ultimately contributing to its demise. The company ceased all commercial flights on January 6, 1988, marking the end of its independent operation.
