Anyone flying QF LH in premium cabins for work or leisure are generating QFFP at a decent rate.
Business BNE-SYD-LHR-SYD-BNE reaps 80,200 for a WP including a bonus 8,000 QFFP
If you purchase that J fare with the right CC you earn 3 x the fare....lets say $9K or 27,000 QFFP. That one return J flight to London reaps > 100,000 points. The cost over and above the cost of the fare to get that 100,000 points is a flat $30 CC fee that QF charges. If you can do it with OPM you've got 100,000 points for around the cost of a bottle of wine.
IMHO the J cabins are awash with QFF members generating huge amounts of QFFP for very little or zero personal financial cost.
IMHO the F cabins are awash with QFF members earning >2/3 the way to WP for the bargain top-up price of $450....the lucky ones got to double that bonanza with a DSC offer and ended up >1/2 way to WP1.
Anyone actively buying points should terminate QFF with extreme prejudice - it's a dog of a scheme for these types of flyers
