No limits, you're only bound by the ONE rules, the rest is up to you to maximise. If you're crediting to QF and have relevant status, there will be specific airline codes you want to book to earn more points, e.g., status bonus.
Myrna,
See the FF rules table and rule 9.5 Status Bonus,
Frequent Flyer - About the Program - Terms & Conditions
eg. on a DONE for a 6000 mile flight (as a Platinum) (HKG-LHR is 5994)
______Base Cabin Status Total
On QF 6000 +3000 +6000 15000
on BA 6000 +1500 +6000 13500
on CX 6000 +1500 ------ 7500
SCs will be the same on both.
Basically idea is you want QF codes first, then BA or AA, then anything else

Thanks, moa999, for the explanation. I understand it now. Hubby is in QFF so he will want all his flights to be coded QF so he gets the FF and SC points . . .
Just to be clear, you don't have to have the flights on QF numbers, just credited to QFF.
