SailorsWifey...SWA will be releasing flights from May 9th to June 28th, 2009 on December 9, 2008 only 22 days away
.
I was lucky a few months ago and went to the "Click N Save" SWA site and found the release dates for future travel. Hope this helps. I usually give myself a reminder a day or two ahead of time so that I can try to get the best price & flight. If a better price comes out later, prior to my trip I rebook at the lower price and get a SWA credit for future flights. Hope this helps.
