"I think this gets less favorable when you compare shorter sectors "

Indeed it does. If based on , say SYD-MEL in business class, it takes 40 sectors to attain the 1200 points to renew Platinum status (40 sectors * 30 SCs = 1200). With the AA scheme it would take about 152 sectors in business class ( 439 miles + 50% = 659 qpoints per sector... 100000/659 = 151.7 flights required )

Comparing cheapie economy, it takes 120 sectors to get Platinum on QF compared with 200 to get Executive Platinum on AA

Also, the comparisons get more marked if you travel ( as is quite common ) a mix of premium class travel with cheap economy since the qpoints for cheapie economy are only 0.5 on AAs scheme

Comapring other premium long distance travel. e.g. MAN-LHR (J) LHR-SIN (F) SIN-SYD (F) SYD-MEL (J) MEL-ADL (J)

SCs earned on QF would be 30+240+150+30+30 = 480. A round trip would earn 960 SCs which only leaves 240 to renew Platinum . Even a MAN-LHR-BOS return in J would earn 260.

If the same trips were done crediting to AA

MAN-LHR = 500
LHR-SIN = 6760 * 1.5 = 10140
SIN-SYD = 3910 * 1.5 = 5870
SYD-MEL = 439 * 1.5 = 656
MEL-ADL = 398 * 1.5 = 597

Total one way = 17,763 qpoints
round trip 35,526

MAN-LHR = 500
LHR-BOS = 3250 * 1.5 = 4875

total one way = 5375
round trip = 10,750

Add this to the previous total and qpoints will be 46,276 which would not even be enough to renew AA Platinum status. Even repeating the whole itinery above would still leave a shortfall of 7448.
