Acerca de Southwest Airlines

Southwest Airlines (IATA: WN, ICAO: SWA) is an US airline.

Southwest Airlines is the world's largest low-cost carrier and the most-flown domestic US airline, known for its open seating policy, no change fees, and free checked bags. Founded in 1967 as a Texas intrastate carrier, Southwest has grown into a coast-to-coast US network serving over 100 destinations. The airline's unique boarding process — based on check-in time rather than seat assignments — is a hallmark of its brand.

Did you know? Southwest Airlines carries more domestic US passengers annually than any other airline and is the only major US carrier that does not charge for checked bags — the first two are always free on every Southwest ticket.
