Perhaps if you only use QFF consider swapping to other FF programs if you are finding award flights difficult to get. Availaibity is there. And with QFF also look at partner airlines and not just QF Metal.
I have no status (or at least have not since I gave up regular business travel), but mainly redeem for F or J long haul flights and mainly via Krisflyer (SQ). I virtually always am able to fly when and where I want, though yes I do mainly book almost a year out.
I mainly these days book 2 tickets at once, but it used to be for upto 5 when my daughters were kids and not adults. Since the Xmas after 9/11 when the 5 of us flew on SQ on the last of my Ansett Points (redeemed 2 weeks before they went under) we have redeemed award flights most years, and sometimes twice per year. Only long hauls I have bought in that period was the JetStar launch Sale of $1 tickets to Bali, with starclass not much extra, and a ridiculously cheap Y flight to New York (where I upgraded for free to PE on the return).
