Its not like this is an overnight event. This slow motion train wreck has been in progress since 2006 when the A332's were handed to Jetstar Int. This was the beginning of the assigned leave programme - 8 years and nothing has changed. Denial & foot dragging on MOU slots, this problem is entirely of managements own making. There aren't many cheap choices to fix the problem now.
As a worthy side note, the A332's were reportedly making $100 million per airframe to and from PER as the boom cranked up. Pure genius replacing them with the busted ar$e classics.
