I certainly hope you're wrong!
I would argue that lgw has been prevented from becoming a standalone organisation and should BALPA achieve its aim of BLR at lgw they would have succeeded in reversing the company attempts to set up a seperate SH operation that would undermine Ts and Cs at lhr.With a common seniority list, mainline pay (allbeit capped) and ultimately BLR it will have reabsorbed into BA.....
SCOPE excludes aircaft below a certain size and I suspect much of the regional work falls in to this category.
Trying to stay with the thread though.... looking at GSS is it a B scale? Well only time will tell I guess but I wouldn't be too surprised to see folk arguing here in the not so distant future about grandfather rights for GSS FOs and captains as BA reabsorbs the work as SCOPE has prevented further expansion of BA generated work....
