Southwest Airlines was founded in 1966 and initially operated 3 Boeing 737 aircraft between Texas cities. It focused on underutilized smaller airports to cut costs and used a single aircraft type to reduce training needs. Southwest pioneered a low-cost model with unassigned seating, no meals, and online booking. It emphasized employee engagement through fun activities and transparency to boost productivity. This highly efficient low-cost strategy has enabled Southwest to remain profitable for over 50 years.
