The latest sale on Southwest Airlines is valid for travel through early March and covers nearly every route in the Southwest network. Sale fares start at $98 roundtrip.

On many routes that have multiple competing airlines, Southwest fares may be lower in certain months than what is advertised in this sale. This is the first time this year that we've seen Southwest's advertised sale extend to include late February and early March travel dates, so you may want to snag these low fares for a late winter break before they sell out.

For most routes, sale fares are valid for travel on Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, through March 6, 2019, with a 14-day advance purchase required.
