@ Hipennine
I share your thought about whether Unite will "do something" about BASSA.
Whilst I know we are all working from limited 'facts', which is why this is a Rumour Forum, it does seem in Unite's, and the wider membership's, interest to try to achieve some form of control over BASSA. I would like to think that some of the questions discussed here are raised during discussions with BA.
However, various 'constitutional aspects' might make that very difficult to achieve. I guess it depends on what's written in some obscure part of Unite's Rule Book.
