EP it is you who is incorrect,
Virgin have at least one ex QF domestic pilot flying with them.
He left of his own free will and is a Captain at Virgin.
The person you refer to is also ex QF and ex AN, he holds a non flying position.
With regard your last line, how do you figure that there is less security?
United, Ansett, American, US Air are or have been in financial strife. The big ones have the most to loose!
