I’ve been sharing the connection only to my private devices so far but there’s no reason why you couldn’t share it with your family on board or even fellow passengers (perhaps for a nominal fee…

I used the BA WiFi on my LHR-IAD flight on Sunday, accessing it through my iPhone: the Mobile Hotspot option on my device (which I use regularly) was grayed out so they must have a means of blocking it.
