DING has a major sale in effect now through all of Christmas day. The fares are excellent: it looks like everything is $99 or less. Travel dates are January 1 through February 16.
This sale is targeted, meaning that you will only get fares for your home airport. See items 14(d) and (e) of the FAQ at
http://flyertalk.com/forum/showpost....0&postcount=15 for more information on targeted sales, including how to change your home airport.
If you don't have DING installed, you might want to do so for this sale.
Item 15 of the FAQ at
http://flyertalk.com/forum/showpost....1&postcount=16 explains how to access DING fares on a computer that does not have DING installed on it.
If you find any hidden sale fares (Ding Daily Doubles, as explained in FAQ item 14c), please post them on the Southwest forum at Flyertalk.
You might also want to keep an eye on Ding on December 31 for a possible New Year's Eve sale.
Everybody have a great Christmas! Now if I can just explain to my wife why I'm spending Christmas eve online making reservations...
