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. Travel to Florida and Nevada is available Sundays through Wednesdays, while travel from Florida and Nevada is available Tuesdays through Fridays. Avoid blackout dates of November 20-21, 24-26, December 21-23, 26-27, 29-30, 2018, and January 1-2, 2019.
All tickets must be booked by Thursday, September 20, 2018, at 11:59 pm.
Please note, these fares are only available on Southwest.com. Other carriers regularly match these sale fares, so be sure to compare to find the best deal.
