Mac users, you are now free to save money on air fare

Southwest recently announced that its acclaimed discount software, DING!, is available for the Mac. For those of you unfamiliar with the program, DING! supplies daily (sometimes, twice a day) offers for flights within the continential United States. Usually, the tickets are a small percentage cheaper than Southwest's normal prices; oftentimes, however, the DING! fares are a substantial discount to the regular fares.

Download DING!, either PC or Mac version, by visiting Southwest's website. Also, if you download the software before April 3, you will receive two free Rapid Rewards points.
