Firstly, I've only read Pages 1, 11 and 12 of this review, so apologies if I've covered something already dealt with.
Second, I have read SFO777's TR on FT... and found it pretty OK although I don't agree with all SFO777's opinions.
Having said that I agree that QF's standards have slipped in the past decade, for the hard product at least, and for the state of the QPs. F on the A380 has rotted on the vine - great when first introduced, tired, very tired now. QF have developed the technique in recent years of announcing upgrades, improvements, etc a number of times and way before implementing, and then taking their own sweet time to implement.
QF however continues to be saved by their staff - always great, and exactly what I as an Australian appreciate. Might not be particularly great for people from different cultures, but we're all entitled to our favourites and opinions.
Mind you as tired and not inspired QF F is these days it just beats the pants of LOTFAP carriers' offerings. You have to go to Asia or Middle East to find better than QF.
