Meburnian1 - which industry were they referring to? The QF flights that I've taken recently have been fairly full......
Given that the fixed costs are (I would guess) a large proportion of the total cost of flying a passenger ex-ADL, surely the more bums on seats, the better? Tto me, as a Silver QFF, flying mostly on the cheaper deals - of the few routes that are still available to ADL-based flyers on Qantas, those to major destinations (i.e. State capitals) have an average reduction of approx 25% in Miles earned, with ALL routes showing a reduction, and 15% average drop in Status Credits earned (3 of the 6 routes are unchanged, so that actual effect is greater than this for the routes that are affected). Hardly much of an incentive for anyone ADL-based to continue to fly with them!
