and, as far as I remember, for all those fare classes on CX flights that earn you miles in Asia Miles, you earn points in QF's program too...i.e. the list of fare classes are the same for both programs, for CX flights...the only difference might be, for all these mileage earning fare classes (Y/B/H/K/L/M/S) on CX flights, you get 100% on Asia Miles...you might get only 70% for some of these subclasses in QF's program...but that would change (to all 100%) anyway later in the year (in September ?)...
do you happen to have a list of subclasses (on CX flights) that you won't earn QF points ? then we can compare...
