The PNR and e-ticket information, which you reference as a "booking" are the passenger's, not yours and thus either the passenger communicates with BA or authorizes you, as a nominee, This could have been accomplished at the time you made the reservations and purchased the ticket.
I'm reasonably computer savvy, but I've no idea what box I failed to tick or whatever during the booking phase to accomplish this, it wasn't obvious. To me anyway. And I know the PNR and surname so could manage the booking, just can't do the most benign thing of indicating we're travelling together.
Anyway, ultimately it's not a big deal in the grand scheme of things.
