Southwest Airlines is a major U.S. passenger airline providing scheduled air transportation in the United States and near-international markets. As of December 31, 2025, Southwest operated a fleet of 803 Boeing 737 aircraft serving 117 destinations in 42 states, the District of Columbia, Puerto Rico, and ten near-international countries including Mexico, Jamaica, and the Bahamas. The airline was founded in 1971 and operates primarily on a point-to-point route structure, enabling more direct nonstop routing compared to hub-and-spoke models, while also incorporating intentional connectivity around core stations.
Southwest is executing several transformational initiatives including assigned and extra-legroom seating launched January 2026, a redesigned boarding model, global airline partnerships with international carriers, a new in-house vacation package product (Getaways by Southwest), 24-hour redeye operations, and expanded distribution through online travel agencies and metasearch platforms such as Expedia, Google Flights, and Kayak. These changes represent a significant departure from the airline's historically uniform open-seating and direct-distribution model.
