Must say my final 2 flights (JQ825 BNE-SYD 9/8/18 and JQ739 MEL-LST 17/8/18) both credited on the 18th September which was significantly faster than I was expecting, backdated the higher rate of miles for a QF DRW-CNS I did in September as well, due to status being increased as a result of those 2 flights crediting
of course small harrumph at there being no way to backdate a lounge visit or extra baggage allowance but I suppose you can’t have it all
mental note to do any status critical JQ flying in the first 10 months of status year only
