Good news if you wanna get away this fall: Southwest Airlines is in the midst of a major sale on dozens of its routes, covering travel between August 25 and December 16 of this year. It's a 72-hour fire sale, though, so you'll have to act before the end of Thursday (June 4) to take advantage.
Travelers can snag advertised round-trip fares as low as $98 on short routes. Many routes, such as Chicago-Minneapolis, Los Angeles-San Francisco and Atlanta-Richmond, Va., showed fares as low as $98 (including taxes). Fares on longer flights appear to increase incrementally roughly in correlation to the distance flown.
As you'd expect with any sounds-too-good-to-be-true deal on airline tickets, there are a few restrictions: no Fridays or Sundays, and the period around Thanksgiving is excluded. (.) But the sheer number of routes available means you might be able to plan a surprise trip across the country on the cheap.
