Google has already given travelers its holiday gift with free Wi-Fi in selected airports. The free Wi-Fi service is available as of today and will remain free through January 15, 2010. The free service will be offered in many of the largest airports in the country including Las Vegas, San Jose, Boston, Baltimore, Burbank, Houston, Indianapolis, Seattle, Miami, Ft. Lauderdale, Orlando, St. Louis, and Charlotte. The airports at Burbank and Seattle will continue to offer free Wi-Fi to all travelers indefinitely.

"We're very happy to extend our Holiday Wi-Fi gift to the millions of people who will spend time in airports over the next few months," said Marissa Mayer, Vice President of Search Products and User Experience at Google. "We know that this is a very hectic travel season for people, and we hope that free Wi-Fi will make both traveling and connecting with friends and family a little bit easier."

The full list of airports offering free Wi-Fi can be found here. Google does warn that users of the free Wi-Fi will be hit with a request to donate money to one of three charities including Engineers Without Borders, the One Economy Corporation, or the Climate Savers Computing Initiative. Travelers can use the free service without donating though.

“Google gets this year’s Wi-Fi Santa award for sponsoring complimentary access in dozens of airports, both to the traveler’s and airport’s benefit,” said Dave Hagan, president and CEO of Boingo Wireless. “In addition to the obvious bonus holiday travelers will enjoy, sponsored access will increase overall Wi-Fi usage in the participating airports and help supplement the airport’s increasingly important non-airline incremental revenue.”
