It's Southwest Airlines sale time, and this nationwide sale is similar to one we saw last week. The deal stretches out into the spring travel window of the airline's booking calendar with fares that start at $98 roundtrip.

Departures are available for travel on Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, through May 22, 2019, with a 14-day advanced purchase required. Travel to Florida and Nevada is valid Sundays through Wednesdays, while trips from Florida and Nevada are valid Tuesdays through Fridays.

As with most sales restrictions, holiday travel at this price is blacked out. Discount fares on these routes not available on December 21-23, December 26-27, December 29-30, 2018; January 1-2, 2019. 

Tickets must be purchased by Thursday, November 15, 2018, at 11:59 pm.

Take note; these fares are only available on Southwest.com. We often see other carriers regularly match these sale fares, so be sure to compare to find the best deal.
