On Monday, I told y’all about the end of the year fare sale on Southwest Airlines, and today I was alerted to another particularly good deal on Southwest. I found out through Smarter Travel that Southwest is announcing a new 48-hour 50% fare sale to Las Vegas. With fares starting at just $70 round-trip, even weary spenders will be tempted to shell out the cash and head to Sin City.

To get these amazing deals, you can travel any day of the week from January to mid-March, but tickets must be purchased by New Year’s Eve (that’s tomorrow, folks, so hurry up if you want to score this deal). Round-trip purchase is required to profit from this fare sale, and tickets must be purchased on the Southwest website using the promotional code “LASVEGAS.” Remember, tickets must be purchased before the clock strikes midnight and you ring in 2009, so move fast.
