But, really, this is a case where WP is not important enough to the decision makers in QF home base.
Yep, just tried to get a first class seat released as a WP on QF10 in October with the cabin wide open. No chance! Rejected within a minute or two presumably by some automatic system.
So the decision makers have outsourced this stuff to a computer algorithm - QF at its worst, yet again treating its most "loyal" customers with complete disinterest.
