1) Where does it say that the extra bag was removed to the hold by the BAA? It doesn't. Whatthefuk only states that he believes 'the problem has been caused by a new policy' of the BAA.
2) What does it state on your ticket? Does it state only one item of hand baggage permitted in the cabin (or words similar to that effect) or is there an additional comment that aircrew in uniform can bring as much as they like, because we don't give a rat's ass about Joe Public?
I'm sorry you bag was subsequently lost - happens all the time - but have no sympathy for you trying to gain an advantage over other pax just because you are aircrew/in uniform.
Frankly, you should know better & set an example. Rant Over!!!
