The initial strategy of Southwest Airlines, famously conceived on a cocktail napkin, was the "Texas Triangle" model. The airline focused on high-frequency, low-fare, "point-to-point" flights between Dallas, Houston, and San Antonio. By avoiding the expensive "hub-and-spoke" systems of major carriers, Southwest could maintain quick aircraft turnaround times (aiming for 10 minutes) and keep their planes in the air longer. They utilized a single aircraft type (Boeing 737) to simplify maintenance and training costs. This "low-cost carrier" (LCC) pioneer strategy prioritized operational efficiency and fun, friendly customer service, effectively democratizing air travel by making it affordable for the average person who would otherwise have traveled by bus or car. This core philosophy of simplicity and efficiency remains the foundation of their business model in 2026.
