About Southwest Airlines
Southwest Airlines (IATA code: WN) is the largest low-cost carrier in the world. Founded in 1967 and headquartered in Dallas, Texas, the airline operates an all-Boeing 737 fleet of roughly 800 aircraft and carries more domestic passengers within the United States than any other airline.
Southwest serves more than 115 destinations across the United States, Mexico, Central America, and the Caribbean. Its busiest operating bases include Dallas Love Field, Chicago Midway, Denver, Las Vegas, Phoenix Sky Harbor, Baltimore/Washington, Houston Hobby, Oakland, Orlando, and Atlanta — which makes it easy to find convenient Southwest flights from almost anywhere in the country.
The airline is known for its friendly service, generous flight schedules on popular domestic routes, and flexible policies: Southwest does not charge fees to change a flight, and fare credits can be reused when plans shift. Our travel agents can help you compare Southwest fare types, apply travel funds, and find the lowest available fare for your dates.
