"Still in the works pending securing the space" is Qantas PR parlance for zero commitment.
Some of my favourite wishy-washy quotes from
this article published just a few weeks ago.
Either you have a series of options, or you need to make sure the space is there - pick one, Cam!
My guess is they are waiting for another lounge operator to forfeit their space OR they are going to carve out part of the existing lounge for F dining like AKL.
LHR F was announced three years ago - to have still not secured a space despite having a 'series of options' is inexplicable.
