flying chick. Can you not see that some of your colleagues, including (yes, I know) the pilots (of which I am one) are trying to warn you of what you are seemingly sleep-walking into. It is a trap.

(Price-fixing is illegal, but BA allegedly did that as well).
To summarise, I and others like me are trying to help you. BASSA's lawyer and your first-class mate are doing you no favours.
