Don't expect the Government to lift a finger. The Nine network and the Packer Press would dump on them if they did.
What you will reead in the press is a delightful article about QF dropping its business class fares in a sudden spurt of generousity to the poor bloody consumer.
This will be somewhat surprising since I was led to believe that QF was breaking even or less on domestic economy and Business class was the icing on the cake.
Furthermore, way back when Compass 1 was starting, I asked the ACCC how long it would take to investigate the issue of predatory pricing if an accusation was made.....I was told a minimum of 6 months.
Considering the huge cashflows necessary to run any airline that is unacceptable.
