Southwest Airlines operates a major U.S. passenger airline providing scheduled air transportation on point-to-point routes domestically and to near-international destinations throughout the Caribbean and Central America, operating a fleet of Boeing 737 aircraft serving over a hundred destinations. The company generates revenue primarily through passenger ticket sales via its website, mobile app, and online travel agencies, supplemented by ancillary services such as baggage fees, priority boarding, vacation packages, and its Rapid Rewards loyalty program, which allows members to earn points redeemable for flights with no blackout dates and provides tiered status benefits that drive customer retention. Southwest maintains a low-cost business model through focus on secondary airports, single-aircraft-type standardization, and high asset utilization, while competing on pricing, route density, customer service, and brand loyalty against major domestic carriers.
