If you haven’t already booked your summer vacation—or if you’re ready to plan a fall getaway—now’s the time to take advantage of Southwest Airline’s most recent flash sale (of which there have been many): their three-day “Fly on the Fly” fare blowout.

Though advertised ticket prices range from $49 to $129 one-way, we found a few fares for as low as $44. The best? A trio of flights from the south's hottest city, Memphis, to Chicago, Dallas, and Houston.

Other great deals include a $79 flights from the airline’s hub at Dallas Love Field to New York City, Los Angeles, Boston, Denver, and Orlando, as well as a $49 flight from San Francisco to Las Vegas, and a $107 ticket from Houston to Belize.

Travel is valid from August 23 until mid December, and blackout days do apply.  Tickets must be booked by before midnight on Thursday, June 9. For those of you who love to book a great deal at the absolute last possible second, keep in mind that it’s 11:59 p.m. for the time zone of the originating city. Click here for more details.
