Southwest

Southwest Airlines is a major U.S. passenger airline headquartered in Dallas, Texas, operating an extensive network of domestic and select international routes. It serves leisure and business travelers seeking low-cost air travel, with a business model historically built around point-to-point flying rather than a hub-and-spoke system. The company is known for policies such as no fees for the first two checked bags and an open seating boarding process organized by groups and numbers. Its website and mobile app allow customers to book flights, manage reservations, check in, track flight status, and access its Rapid Rewards loyalty program. Southwest operates a fleet composed primarily of Boeing 737 aircraft, which simplifies maintenance, training, and scheduling operations across its route map.
