Planning a winter getaway? If you live near an airport served by Southwest Airlines, the current three-day nationwide sale could save you big money on airfares for travel between December 9 and February 28, 2009. Here are some sample one-way fares:

• $49 between Phoenix and San Diego
• $69 between Las Vegas and Oakland
• $79 between Oklahoma City and St. Louis
• $89 between Detroit and Orlando
  

The kicker with these promotions, of course, is that you need to act fast and seats are limited. You must book by midnight CST on Thursday, November 20.
