Southwest has launched a nationwide sale, with fares as low as $49 one-way direct. Sale prices are good for select days between August 20 and December 18; see “Travel Dates” below for more specifics. While not every route is available, pretty much every mainland city that Southwest serves has at least one-deal. I saw mainland because only inter-island flights Hawaiian flights are included, not flights to/from the mainland. As for what is available, international flights as well as domestic flights (including non-stops) show deals, and the prices can be very good, especially considering Southwest’s “Bags Fly Free” policy.

Whenever Southwest hosts a sale, make sure you check any existing flights you have already purchased. Southwest has no change fees, and if the sale price is lower you will receive a credit for the difference usable for future SWA fares. Plus, if you are unsure after you buy one off these flights, remember that any fare marketed in the US is free to cancel within 24 hours. But this sale has a short window, and rices are only good until 11:59 M Pacific Time on June 6, so act fast.
