At the launch of Virgin America's service--yes, their virgin flight--they openly discussed having AirCell in-flight broadband next year: This, according to Xeni Jardin of BoingBoing, who reported from their launch. She confirmed via email that AirCell was being openly discussed by Virgin America as its Internet supplier. She noted in her BB report that the planes have two 110-volt outlets for each three seats in coach, one per seat in first class; Wi-Fi access points in the front and rear; and Ethernet at every seat. There's onboard chat services, too, to allow intraseat communication. There will also be pay-per-download music sales. They'll also deliver other Internet content onboard, presumably via a caching media server or proxy server.
Jardin also notes that the plane is, you know, comfortable. Lighting isn't harsh: "The cabin was softly lit on our daytime flight in purple and pink, the mood lighting is different at night." Their initial routes are between SFO and LAX, JFK, Dulles, and Las Vegas; JFK and LAX; and LAX and Dulles. (Can we beg them to enter the Seattle market for nonstop cross-country?)
Contacted for comment, AirCell said that they are in discussions with several airlines, that they neither confirm nor deny arrangements with any non-announced airline, and that they are covered by non-disclosure agreements with the companies with which they are negotiating, and thus can't provide any detail until such point as a contract is final.
