Like Colster, I too earned my WP status flying discount Y - QF all the way except when they didn't fly the route. Sure the F lounge was crowded at times, (the domestic lounge was like a front bar more often than not!!), but the extra perks that came with the WP status usually made the pain, that much easier ...
And there will be many more in similar situations to yourselves who, depending on their Y routes, may have to make a decision to do even more flying than they do now in order to maintain WP, following the most recent enhancement ... or else drop to SG, and no F Lounge then.
And when will QF review (raise) the SC requirements for WP anyway, putting that out of reach for many (say 1800 SC for SG and 2500 SC for WP), and therefore creating even more space in the F Lounge for the most deserving?
Just my thoughts.
