the domestic config 330's have the worst J product I have experienced in the QF fleet. I wouldn't pay or use points for it any more. It is only marginally better than Y and not better enough to justify the cash or points. I have done 6 trips to Perth this year, most of which have been in J. Each time I would try and tell myself that it was just unlucky to have such a rubbish flight. Yet have only had one bad Y flight.
