Most airline fare sales are mostly marketing. The prices offered aren’t anything out of the ordinary; you can often find the same prices before or after the sale is over, and sometimes the fare sale doesn’t provide much of a discount or incentive to book.

But this recently announced fare sale from Southwest is somewhat different and is definitely worth checking out.

Southwest Fall Flash Sale – 40% Off!

Southwest has just announced a new Fall Flash sale, with up to 40% off flights

Here are the terms and conditions of this Southwest 40% off fare sale:

  • Use promo code LUVFALL by 8/7/2025 (so book before this Thursday)
  • You must travel between 8/25/25-1/26/26. for most flights
  • The 40% discount applies to the base fare, and not to taxes and fees. This makes it slightly less than 40% off, but it’s still a good deal
  • The promotion applies to Basic and Wanna Get Away Plus fares as well as using points

The Bottom Line

This sale is good for both cash fares as well as for tickets booked through Rapid Rewards points. Keep in mind that the discount is advertised as “up to” 40%, and there isn’t an award chart, so having a sale with a percentage off isn’t exactly ideal. Still, in doing a bit of looking around, I was able to find some decent deals. This sale does give the opportunity to cancel or change a flight and rebook it, but keep in mind that Southwest’s flight credit policy is now more restrictive depending on the fare you purchase. Still, it is possible to change your flight and possibly save some money if your fares are lower now.
