Even if another airline and /or an MRO approached JHAS to do overflow work(12months or 6 months ago). And even if that overflow work was enough to replace the Jetstar slots, it still would have not made any difference in the outcome of JHAS.
Leighton/JH did not win those 2 billion dollar contracts at Melbourne airport. So no big contracts, so no need to keep such a big property investment on the airport.
Its a shame that the dollar is highest priority, but thats why we create a business...for the dollar.
