Google is now a wireless carrier, working with airports across the country to provide free wireless from now through January 15, the company said Tuesday.

Currently, the wireless will be available in 47 airports including: Las Vegas, San Jose, Boston, Baltimore, Burbank, Houston, Indianapolis, Seattle, Miami, Ft. Lauderdale, Orlando, St. Louis and Charlotte. Google is working with Boingo Wireless, Advanced Wireless Group, Airport Marketing Income and others on the initiative.

Google further said it will give network users the option to donate to Engineers Without Borders, the One Economy Corporation or the Climate Savers Computing Initiative. The company said it will match donations made across all the networks up to $250,000, and the airport network that generates the highest amount per passenger by January 1 will receive $15,000 to donate to the local nonprofit of their choice.

Google is also partnering with Virgin America to provide free wireless on every Virgin America flight between November 10 and January 15.
