please - the key to the previous quote was "real" ... those things would be coupled with either J booking anyway, which is what is typically often required to hit the WP tier (remember WP isn't just the next 10 SC up from Gold ... it's X2 (ie, effectively within 6 mths!!) -- so (at least some -- if not a fair bit) of your booking is already at premium level, so you're not getting that much they wouldnt already be giving you!
esp if you consider the freedom you have to spend what would have gone to securing the other 600SC into other carriers (at better prices, quality, and service ... Y and J ... then really, what's the point of holding on just to get QF WP when you'd be getting all those perks anyway - either with them, or with someone you choose.
really, it's clearly rationalised down to a two tiered system - nothing (bronze/silver - although silvers get free tags, bronze+ QP need to buy theirs ... in both cases they check themselves in now, tho) and elite (gold/platinum - although platinum gets one piece of extra luggage and j/f access when they fly as QF platinums ... something they'd likely to be getting anyway if book into J (with one exception - F lounge, if a international flight), tho) ... it's just a lean, mean model that keeps them profitable against a market where everything else is LCC, without having to appear that they've gone down the same track.
