According to Aviation Centre:
There are big plans for Jetstar.. Most of the 100+ B787's ordered by the Qantas Group were destined for the low cost operation.....Australia's Jetstar has no doubt that the long haul path is the way to go says CEO Bruce Buchanan. 'Future long-haul expansion to Europe is a great opportunuity for Jetstar'.
And there is nothing compelling Qantas to keep the jobs in Australia.
