I think you will find as well there has never been a separate financial report for JQ long haul...
Given all the new toys but their traffic stats have never been as good as mainline in places such as Japan ~ and they are frequently known to have 2 for 1 deals etc.
As for EK, I imagine one of the ideas was - if you can't beat them, at least neutralise and ?profit out of one of your biggest and most aggressive competitors! This then allowed a refocus on high growth areas (Asia) and high cost competitors (USA) where QF can actually make money. Domestic oncarriage from EK also would have been major compared to BA as mentioned (~100 flights/week compared to ?7).
