A mate of mine who got his fingers burnt with P2F, said BALPA were interested in Cadet exploitation and were investigating - he contacted them. Know nothing more than that, however, what I would say, is that seeing as these schemes exist and have done for a couple of years or so now - I would think (point raised many times before) that there is a legal loophole that allows airlines to get away with it - maybe Balpa are well aware of this and feel they can only pressurize an airline to do the right thing but not force them. That said there is nothing stopping someone naming and shaming such airlines and schemes in the press - in fact I can imagine a nice dispatches programme about it all.
