scr1, I fully appreciate that those on the ground are also in a terrible position at the moment, and financial hardship may well be upon them, so please don’t take this as anything other than an observation:
As I understand it, the charity was set up by serving (and crucially, ‘safe’) BA pilots who felt they wanted to help their (hopefully temporarily) redundant flight deck colleagues, all of whom are junior and many of whom are still laden with large training debt, and who may have been safe had LIFO not been used. They are now looking for funding, the idea being that other BA pilots are the primary source of donations. Other donations welcome, of course.
Perhaps a branch within the charity could be set up for other work groups, or even advice given from the founders of PT to those wishing to set up a similar charity for their workgroup?
