Southwest has launched a birthday sale, with fares as low as $49 one-way direct. Check your email for the subject “Celebrate our birthday with a fare sale”; the sale is also available from Southwest’s website. Sale prices are good for select days between September 3 and December 18; see “Travel Dates” below for more specifics.

While not every route is available, most mainland cities 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. Past sales have those flights as low as $29, though this time they are $49. 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. This sale comes along at a perfect time to help you earn extra Rapid Rewards miles with your Chase Southwest card. Make sure to check the calendar for prices, as the actual fares available are often lower than those advertised.

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 20, so act fast.
