Credes 'metered' post was three minutes before my 'How come' post, but mine took about ten minutes to compose, so I had no opportunity to see it before I posted. But thank you for pointing it out.
As the network connection for portable devices will be ever changing, these settings (of the sort I described) need to be at the fore.
As I mentioned, the OS could probably guess. So the airport wifi would allow certain OS activities, the Inmarsat wifi on the aircraft would allow nothing but human access. A simple dialog box to confirm and adjust. This should have been built into the OS at least five years ago, if not ten.
