Remember that the Game Change Program was arguably brought about by QF's over-investment in JQ which led to DJ having to transform into VA and move up to be a full-service carrier.
Rewinding from that - remember that JQ and all its "LCC flag offerings" (including deliberately piss-poor service, draconian customer service recovery and nickel & diming) was designed to compete head-on with DJ.... AND to muddy the waters and leave a bad taste in the mouth of consumers who didn't like the LCC approach.
It wasn't just JQ that wore the opprobrium due to JQ's reputation DJ (as the other discount carrier) wore it too, through no fault of their own. The strategy was very deliberate to push service-conscious consumers to QF.
So DJ was forced to act and that's why we have VA.
The problem was that VA ran out of money to weather QF's aggressive defenses, whilst at the same time gaining a profitable market share as a full service carrier.
Now we're seeing the results of that where VA has also run out of ideas - so we see the aggressive cost-cutting in the air, and a few mismanaged and misdirected loyalty changes (amongst some positives). Basically - we're seeing scrambling and desperation.
The result is that VA has decided to return part-way towards being a LCC/Hybrid in an effort to reduce costs - except that they cannot compete on JQ's cost-base, and they seemingly no longer want to compete with QF - yet often charge close to QF fares.

Now - that said - VA have a superb transcon product and forced QF to lift their own game. VA also now have a superb transpac J product - which they previously struggled to sell, but with The Business may actually improve their results.
VA also excels at PB and forced QF to lift their game (if only in signage rather than implementation).
For a purely domestic Golden Triangle or transcon flyer - VA is arguably still a competitive choice as preferred carrier (recent moronic loyalty decisions aside).
Yes - the J product isn't as good as QF's - but it's generally cheaper on the Golden Triangle too.
The problem isn't as simple as deserting VA for QF.....
Without a competitive VA taking the fight to QF in the premium space - it's only a matter of time before QF reduces amenities and services too. Let's not forget how bad QF's 'snack flights at meal time" flights were just a couple of years ago.
My prediction is that right now - is the peak of QF service domestically. Standby for future enhancements.
