CASA will absolutely require some new, qualified and sturdy Flt Ops girders before Mr Biggs proposed rapid expansion and particularly the A330 inclusion occurs.
I suspect the backroom deals required VA to expand Tiger instead of launching a new LCC AOC, which would have cost much less than the Tiger buy-in.
The baggage history is the hidden cost Mr Biggs, be careful, it has sunk other ships.
Nothing bites as deep as a Tiger sensing its end.
