Southwest Airlines is having a busy week with three different sales released today. This one is for their Nationwide Seat Sale that is valid for travel in late summer and fall months. This sale falls in line with Southwest's usually weekly offerings, but the prices in this sale are much better than the ones from previous weeks. No flight listed in this latest discount offer is more than $198 roundtrip, with many fares ringing in at $118 roundtrip.

Seats are available on Tuesdays and Wednesdays, (but other days may be available) from August 13 through December 19, 2018. Flights are blacked out on August 31, September 3, November 20-21 & November 24-26, 2018. As always, pack all you want because Southwest still flys two checked bags for free.
