Southwest has launched another fall sale with some more good deals between city pairs. The sale is available from Southwest’s website. This sale is very widespread, with seemingly every departure city featuring at least one deal.  Unfortunately, flights to Hawaii from the mainland are not included. Make sure you plan travel early: these fares require a 21-day advanced purchase (14 days interisland), but are good for September through March travel.

Don’t just accept the price noted on the sale page: as is often the case with SWA, lower prices are available on the “low fare calendar” pages. While not every deal is lower than competitors, the addition of free checked bags turns a lot of these into solid savings for family travel.

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 prices are only good until 11:59 M Pacific Time on September 12, so act fast.
