Simple accounting trick.
For years Qantas refused to properly write down assetts including their aircraft fleet then last finanial year wrote them off the books and annouynced a record loss. Now they can report that without the depreciation they are back on the track to prfitability. In reality they have only cleared the decks of the deck chairs and the lifeboats on the Titanic.
Definitely financial smoke and mirrors on an airline that flies to fewer destinations than before relying on codeshare to con the passengers that still buy Qantas tickets.
