As of 2015, Southwest Airlines is the only airline offering Wanna Get Away flights. Other airlines offer discounted airfares under different names, such as the Discount Den program from Frontier Airlines or the $9 Fare Club from Spirit Airlines.
Of the various types of airfares offered by Southwest Airlines, Wanna Get Away tickets are relatively inexpensive but include a number of restrictions. The discounts on these tickets can be considerable--well over half off the full price for a given ticket. As an illustration, tickets between Philadelphia and Orlando may run as low as $44 using a Wanna Get Away fare and as high as $491 for a full-priced Business Select fare, as of 2015.
While one may request a full refund of Anytime and Business Select fares, any money paid toward a Wanna Get Away ticket may only be used toward a different Southwest Airlines flight. Other restrictions involving standby travel fees also apply to these discounted fares.
