In North America, the dominant brand for in-flight WiFi is GoGo, the brand created by long time communications company, Aircell. Today, when I read the story about United Airlines adding in flight WiFi to some 300 planes and I read Panasonic as the brand involved I noted the omission of GoGo from it. While the new got some good pick up, only TechRokies.com, the regional technology news site coveing the Colorado Front Range tech scene noted it.
Over the past few years United has been deploying GoGo on their coast to coast and longer haul flights, but not much else. Their Star Alliance partner, Lufthansa has already announced and has deployed the Panasonic service, which uses satellite communications versus air to ground CDMA based technology.
Looks like to me, other airlines that have an International route system may go with Panasonic, over Aircell, unless Aircell comes up with a global solution.
