Google has announced a deal with three major US airlines to provide free inflight wifi over the holiday season.

The search giant said November 7 that passengers flying with AirTran, Delta and Virgin America would be able to use the inflight wifi provided by Gogo Internet free of charge, from November 20 through January 2.

As all three of the airlines have outfitted their entire fleets with the equipment, Google predicts that the Google Chrome-sponsored promotion will reach some 15 million passengers on board more than 700 aircraft.

The scheme is a significant expansion of a similar program last year, during which Google offered free internet on Virgin America flights and at 50 US airports.

Inflight internet access has become widespread in the United States and connection fees can be as low as $11.00 (€7.90) for a 24 hour pass using the Gogo system.

In a sign that predictions of an international boom in connectivity are set to prove correct, Canadian wifi provider SkySurf last week announced a deal with Gogo that will allow passengers to use inflight wifi in both countries, switching seamlessly between the two networks as they cross the border.

SkySurf is set to launch its inflight connectivity services with Canadian airlines in 2011.
