Lesson Summary. Southwest Airlines is a popular American airline that is well known for its friendly service and low prices. There are a number of competitive advantages that have helped make Southwest a successful company including its low operating costs, flexible customer approach, and employee focus.

Southwest Airlines built its competitive advantage through a "Low-Cost Carrier" (LCC) model centered on operational efficiency and a unique corporate culture. A key pillar of their strategy was the use of a single aircraft type, the Boeing 737, which drastically reduced maintenance costs and simplified pilot training. Unlike legacy carriers, Southwest utilized a point-to-point route system instead of a "hub-and-spoke" model, allowing for faster aircraft turnaround times (often under 20 minutes) and the use of secondary, less congested airports. Furthermore, Southwest fostered a highly productive, "fun" workforce that remained non-unionized longer than competitors, leading to higher morale and better customer service. Their famous "Bags Fly Free" policy and lack of change fees also created deep brand loyalty, positioning them as the "friendly" alternative to carriers that relied on nickel-and-diming passengers with ancillary fees.
