After taking a week off for the holidays, Southwest’s sales are back. This week’s sale is called the “4-day sale” and is available through their website.

As usual, there are deals below the advertised price, and potentially below the “sale page” price as well. Flights from Greenville/Spartanberg to Atlanta are $45, below the $49 sale listing. Or between San Francisco and Boston, advertised at $108 but available for $108! Perfect for escaping the cold, or seeing some history, either way.

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 of these flights, remember that any fare marketed in the US is free to cancel within 24 hours.

This sale ends Thursday night (January 2) at 11:59 M Pacific Time, so you’ll have to act fast if you want a deal.
