American Airlines ran a "dress rehearsal"
of its AirCell-powered
in-fight WiFi service last month, and it looks like it was a success -- the airline is set to expand the trial to some 15 jets over the coming weeks, with tests expected to last six months. The tests are apparently more to evaluate the speed and reliability of the wireless connection, rather than to study the impact on the plane's avionics, so it looks like this is finally happening -- we'd recommend against wearing your WiFi-detector shirts
through security, however.
