We did a search on the Southwest Airlines website and found they provide information on several types of discounts and special promotions. Many of the PROMO CODES relate to saving on rental car fees when you book airline travel with Southwest… but we did find one that is just a straight 10% off on airfare, (SAVE10),

Note: the 10% off code can’t be combined with other specials, so make sure there isn’t a better deal before using the code.

To find their promotions or travel deals, go to www.southwest.com and click on the “Special Offers” tab.
