Southwest Airlines — Network & Service Overview
Southwest Airlines is a US low-cost carrier founded in 1967 and headquartered in Dallas, Texas. It operates as an independent airline without membership in any global alliance. The carrier serves 121 destinations across the US and 10 international locations, primarily in Mexico, the Caribbean, and Central America. Southwest’s fleet consists exclusively of Boeing 737 aircraft, which simplifies operations and crew training. While not a traditional network carrier, it is the largest US domestic airline by passenger volume due to its extensive point-to-point network and focus on domestic routes.
Southwest’s route network is centred on seven primary hubs: Dallas Love Field (DAL), Chicago Midway (MDW), Houston Hobby (HOU), Phoenix Sky Harbor (PHX), Denver (DEN), Las Vegas (LAS), and Nashville (BNA). These hubs allow the airline to connect smaller markets with larger cities efficiently. International services extend to destinations such as Cancún, Montego Bay, and San José del Cabo, among others. Southwest does not participate in codeshare agreements or alliances, meaning its routes and partnerships are limited to its own operating certificate and select interline partners for baggage handling.
Southwest is distinguished by its no-frills cabin product, which lacks premium economy or first-class seating. All passengers receive two free checked bags, a rarity among US carriers. The airline operates a point-to-point rather than hub-and-spoke system, which can result in more direct routings but may require connections for less common city pairs. Boarding follows an open-seating policy based on numbered groups assigned at check-in. While it does not offer assigned seats, passengers can select seats at no extra cost during online check-in. International flights require a passport for all destinations.
