Correct me if wrong but Alliance are turning a profit??
If so no mean feat in aviation at any time.
They are part owned by QF, if as some suggest QF take majority shareholding fair to suspect like others they will become second hand A320 operators in the years to come.
For now they are competing in a price driven market - and succeeding.
Yes at some stage they will have to change equipment - but not for quite a few years to come.
The future's not that important right now, much can happen.
