Not all systems are go, but starting today, many of American Airlines' flights are Gogo equipped, the new service offering in-flight wireless internet access while traveling above the clouds. All 15 of American's Boeing 767-200 jets traveling from JFK airport in New York to destinations in Los Angeles, San Francisco, and Miami are up and running free of charge to passengers, with pricing set for $12.95 (flights over three hours) and $9.95 (flights under three hours) once the service officially launches in a couple of weeks. Using a version of EVDO Rev A technology, Gogo equipped jets will communicate with a network of 92 cell phone towers nationwide. If the rollout goes smoothly, American Airlines indicated it would expand the service throughout its fleet.
