About Southwest Airlines
Southwest Airlines is the largest low-fare carrier in the U.S. and flies a point-to-point network with focus cities rather than traditional hubs. Policies on bags and seating have changed in recent years, so always check the current rules.
Where it is strongest
Very large domestic network, many cities that other major airlines skip, and no codeshare complexity because it flies its own flights.
Booking tips
Southwest does not list its fares on every third-party search engine, so ask your agent to check it directly. Confirm bag and seat rules at the time you book.
