Book a $49 Southwest Airlines flight by August 12.

With the Southwest Fall sale, from now until Aug. 12, book a one-way Southwest flight for as low as $49. There is a limited amount available, so hop on that now!

The discounted flight has to be between Aug. 24 – Dec. 16 for the continental U.S., Aug. 24 – Dec. 16 for Hawaii and international flights, and Aug. 24 – Dec. 9 for Puerto Rico.

A 21-day advance purchase is required.

Here are some of the cheap flights I found:

  • Denver to Salt Lake City – $49
  • Burbank to Las Vegas – $49
  • Phoenix to Palm Springs – $49
  • Boise to Seattle – $58
  • Dallas to Tampa Bay – $59


There are some blackout dates, so no cheap Thanksgiving flights.

Unfortunately, there are a few dates that are totally blacked out. Probably for good reason, since they’re all around Thanksgiving. Avoid the crowds and avoid these dates:

  • Nov. 19
  • Nov. 23 – 24
  • Nov. 27 – 29
  • U.S. to Hawaii Nov. 18 – 21
  • Hawaii to Nov. 26 – 30



Canceling your discount flight? No refunds. But you can get a credit.

According to the fine print, you can’t get a refund if you cancel once you’ve booked your flight through the Southwest sale. But you’re not totally out of luck, since you can still apply the canceled flight as a credit towards a future fare as long as you cancel 10 minutes before your flight.
