Southwest Airlines has launched another three-day nationwide sale on summer flights with fares as low as $39 one-way and $78 roundtrip.
Now through Thursday, May 7 at 11:59 p.m. CT, travelers can score deals on travel within the continental U.S., interisland Hawaii and to and from San Juan, Puerto Rico for travel from May 19 through October 30, 2020, and travel between the continental U.S. and Hawaii from June 7 through October 30, 2020.
Keep in mind that the discounted seats require a 14-day advance purchase, and continental U.S. travel is not valid on Fridays and Sundays, except where otherwise specified.
The cheapest fares are available on Southwest’s interisland Hawaii routes, including Honolulu-Kona. However, customers can still find roundtrip flights within the continental U.S. for under $100, including on nonstop routes such as Atlanta-Nashville, Fort Lauderdale-Orlando, Los Angeles-Phoenix and Baltimore-Boston, among others.
International fares have also been slashed, with nonstop one-way flights to Cancun, Mexico from Chicago, Denver, Fort Lauderdale, Houston and St. Louis available for $232 or less.
