Google has announced its holiday "gift" to millions of travelers: free Wi-Fi now through January 15th.  The search giant is sponsoring the offer at 47 airports nationwide and on Virgin America flights. While you're waiting to board, Google hopes you'll make a donation to any of three participating nonprofits: Engineers Without Borders, One Economy Corporation, and Climate Savers Computing.

Not to be outdone (and looking to increase its visibility among Web searchers), Microsoft Bing is partnering with JiWire to offer free Wi-Fi at airports and hotels in exchange for one Bing search. —Nick K. Mandle
