Just my best guess really. With VA bleeding the cash reserves and with no real prospect for a change in their circumstances,the bottom line doesn't look too good.
VB have the might of QF, J* and Tiger continually gnawing away at their market share. Most of the remaining money in the bank will be consumed setting up the 330's and the introduction of the new brand. A new business class including uniforms,lounges,livery will not come cheap. The death knell will come when the Labor government approves SQ to fly across the pacific.
VB may very well survive,although I believe in a much smaller version with PB style pay and conditions. Don't get me wrong I think JB had little choice than proceed
on his present path, unfortunately their are far too many forces acting which are beyond his control.
