The good will leave at an accelerated rate, the crap will stay as they have no choice. End sum QF will be on a crash spiral. The QF premium ticket price will be lost when the traveling public find there is absolutely nothing that distinguishes them from most other carriers.
Keep the engineers maintain the premium, dispose of the engineers and lose it, net sum to the company a possible quick short term gain for Geoff and co if we bend over but a long term problem with ticket premium when all is revealed.
So why would I help Geoff and co to another huge paycheck!
