Our Google overlords have spoken, and there shall be free wi-fi in airports for the holiday season.

Through a partnership with many of the providers that already power most airport wifi, albeit for a fee, Google is making wifi free at 47 airports through January 15, 2010. The service is in conjunction with Boingo, Advanced Wireless Group, Time Warner Cable, Electronic Media Systems, Lilypad, and individual airports.

The list of 47 is somewhat deceiving. For example, Charlotte already offers free wifi, so now there’s a Google-branded free option. Big whoop. But at others, like Boston, free service is new — and very welcome.

Unfortunately, some of the biggest airports aren’t on the list. Chicago, New York, Los Angeles, Atlanta, San Francisco?… Nope. Alas.
