About Southwest Airlines
Southwest Airlines is a Dallas-based low-cost carrier that flies mostly within the United States. Rather than funnelling traffic through one or two very large hubs, it spreads its flying across many bases such as Dallas Love Field, Denver, Las Vegas, Baltimore, Chicago Midway, Phoenix and Houston Hobby, and it sells a lot of point-to-point trips. Beyond the mainland it serves Hawaii, Mexico, Central America and the Caribbean. Southwest has no alliance membership and operates a single economy cabin, with fare bundles that differ in flexibility and extras.
Southwest historically sold most of its seats through its own channels, so its presence in third-party systems is more limited than that of other US airlines. On IATA.co, Southwest Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates, and you should not assume they will be there for every search. Searches run live in the booking portal or through the flights API, and confirmed bookings are paid from your prepaid balance.
