Southwest is at it again, offering discounts on more than 1,000 routes for flights between August 23 and November 2. One-way fares for fall travel are as low as $44 (think Atlanta to Greenville, South Carolina), and some of our favorite deals include a $112 trip from Long Island to Orlando, a flight from Los Angeles to Liberia, Costa Rica that costs only $174, and a $170 flight from Denver to one of the world’s friendliest cities: Puerto Vallarta, Mexico.

You have until May 19 to book your trip, but we wouldn’t wait long: the best deals are likely to sell out quick. And considering the regular fare sales Southwest is known for, you may want to consider signing up for the airline’s Rapid Rewards loyalty program. You could end up earning a Companion Pass for two calendar years.
