Ding

If you fly Southwest Airlines, this is a great one for you! Run this app in the background and whenever airfare deals come through for your airport, you’ll be notified with a friendly “Ding”. (It’s the same sound you hear when the captain turns off the fasten-your-seatbelt light.)

This app has been available for Windows for a while, but was just released for Mac OS X today.

If you download the app by April 3rd and keep it running for 30 days, Southwest will deposit two Rapid Rewards credits into your account, and that goes for Windows users too. (More information)
