LGW 747-400 "mini cabin"

hi everyone
in the v.2 747-400 (LGW-LAS), there is a "mini cabin" in Economy, at the very front of the E section, just behind PE.
does anyone know when these seats become available for selection online?
I remember last time I booked these, they were greyed out/taken in the months leading up to departure day, it was only when I casually checked our seats a short while before departure day, I noticed nearly the whole "mini cabin" was available for selection.
I much preferred sitting here as it was a little more peaceful!
