American Airlines test of Aircell's Gogo in-flight broadband service apparently went well, so the airline has decided to expand the service across its fleet. According to the carrier, they'll be installing the service on more than 300 additional planes, 150 of which will be completed this year. 300 is about half of American's total fleet -- and it's the planes that don't fly over water, staying within reach of Aircell's EVDO-based system. The service costs $7.95 for smart phone access on flights of any length, $9.95 for regular access on flights of three hours or less, and $12.95 on flights of more than three hours.
