They're running the same $49 / $99 / $129 / $149 sale they've run the last few years, which covers travel to Atlanta during ProgPower... however, apparently this has sparked such high demand that their website has slowed to a near-halt. Looks like the deal is only available through Southwest's website, not through any 3rd-party travel websites. Unlike years past, no other airline has matched them (yet), and the last few years, this deal has worked out to a round-trip flight for $98 for me... so I guess I'll keep trying today and tomorrow.
