When VA upgraded the B777 business class they said they were doing it because of the premium they would/could charge.OT slightly, but I wonder how long it will be before we return to those rather unpalatable fares that were the norm nearly 2 decades ago. Qantas ruled the southern sky and SYD-LAX return airfares averaged $2500 per person on a good day.
Then V-Australia entered the field and the game changed.
I can't help but think that low fare wars are all very nice for the passenger, but relative to our population - truly unsustainable over a long term.
However, you can still get the fares are circa $6k in selected sales. So it's not really worked from that angle too.
The only way I see AUS - LAX fares going up is if the AA/QF tie up gets rejected. Also when the QF A380 is out out the pasture ... so 10 years plus.
For me in Perth all my flights to the US are actually on SQ and it's make better sense (mainly timing) going via SIN. From the East Coast you have Air New Zealand options etc. etc.
