Flying for the holidays? You'll be able to tweet that fact to the world for free this year, if you're flying Delta. The airline has teamed with both eBay and Gogo Inflight to offer 30 minutes of free wifi on all wifi enabled planes through January 2. That means free wifi on all domestic flights, though not on all international ones.
A nice holiday gesture, I think. If I were flying Delta this season (I'll be driving), I might consider tweeting a thank you to the all the parties involved. Safe travels all!
