Never trust the reservation system if you're flying United. Unbeknownst to me, until I was seated was the fact that my San Diego flight to Chicago would have WiFi on board.
While United is not using GoGo, or Row44, they are using their own system, and since they are part of the Star Alliance, I'm suspecting they are using he same technology as German partner Lufthansa. That means the Panasonic technology and a connection via satellite, vs. to the ground.
Only issue--I could not log on with my Java less Mac Book Pro retina, but I could with my iPad 4.
Speeds were good, but most of all i was Staying Connected.
