So booked SAN-LHR in December (First). Is this normally a mid-J or High-J config? Seems one can no longer see seatmap by doing a fake booking?

On the return we are on 787-9 in F (SJC). Will monitor if I can find F out of SFO or SJC but otherwise the connection is worth it for me to get on a 747.

Did BA F round trip this last Christmas trip and we both really liked it. Yes the seat isn’t Cathay but we found them very comfortable and the service was excellent!! And the FAs all super friendly.
