uhhh, I think she means that her CX flight is booked in Q, not QF. From my limited experience, deeply discounted economy tickets don't accrue AAdvantage miles.
Generally, if your fare basis can't get mileage credit on one OneWorld airline partner (and CX certainly counts here!), there is little chance of getting credit on any of the others (QF, AA etc.)
