You really need a solid education in corporate business practices. ROI. The 777-200LR aftermarket is zero value. They can't be sold to anyone, so the only other option is to run them into the ground. However, that does come with the question of why they'd fly such a long route on such an inefficient bird. There is no member of Sky Team that flies an A350 into Sydney, therefore Delta would have to pay top dollar to Singapore Airlines or someone else to get hangar and maintenance resources. There are plenty of 777s flying into Sydney from all 3 alliances, meaning that commonality benefits from a local economy of scale.
If the engineers ruled the roost, airlines would lose money without a doubt. Sometimes the most optimal solution is not one that makes sense financially. Unless fuel prices spike up that badly, they can keep taking the profits on the route that they have and hold off on increasing their operational costs at Sydney. Sheesh and I'm supposed to be cold-hearted engineer on this forum, not the one explaining Business 101 to someone who thinks insults make for good arguments.
