"QF & AN FOs' pay were and are quite unsustainable for LCCs............."
Who on earth said that?
Care to have a look at Ryanair salaries?
If you do you will see how wrong that statement is.
Did you mean unsustainable in the current climate of oversupply?
Australian aviation is certainly oversupplied with pilots willing to work for very little.
I suppose if you were looking at it from the perspective of market forces you'd be right, only you did say 'were'.
Mind you, I can't for the life of me figure out why anyone would want to work for Virgin Blue.
