Which begs the question ...
Primarily there are only QF and VA plus their fully owned LCC divisions
So on that "duopoly based structure" why are they both not charging reasonable fares on domestic operations
Understandably there is more competition on international sectors, but even many that VA operate have little aggressive competition
Imagine if you will, a true LCC setting up here in Oz and what it would do to VA
Likely the same as what VA, Compass and Impulse did to Ansett
Without going down the road of colluding or price fixing, little would need to be done to have a strong domestic duopoly
Say VA with their fleet of 110 odd frames added just $2 per domestic sector
110 frames
100 pax average (probably higher as most are 180+ seats)
5 sectors per day
365 days per year
$20 million per year
Or add $5 and it's $50 million
This would go an awful long way to getting them into the black
