Slight detour: In-flight internet isn't done by satellite only. There are newer technologies available that connect an aircraft at cruise altitude to LTE networks on the ground using special upward pointing antennas that cover a radius of about 150km. That obviously works over land only, but delivers decent enough throughput. Aircraft antennas are being installed on the bottom of the fuselage. Much cheaper also for airlines. If you're interested in the details, google "Nokia A2G" for example. The system has been rolled out throughout most of Europe (
European Aviation Network/
EAN), I don't know about China. But Chinese companies are leading in mobile network tech, so I'd presume they have something like that.
