- You can compare the DFW-SYD (7450 nm) to the current LAX-MEL (6900 nm) and get some ball-park figures. The extra 10% seats seems about right at the suggested 380 seats + bags for the A380 direct. No freight on either the current service to BNE or the A380 direct SYD.
- Adding about 15 t you'll get a fuel order at DFW of about 235 tonne give or take, and you'll depart at the max BRW of the aircraft as opposed to the restriction on the 744.
- Won't normally be able to handle any weather or alternate requirements at SYD (as now), and will probably have an exemption on ATC holding. Brisbane will be the enroute refuel point of choice, though if it is used, then duty times will get tight.
I think that's about it ... estimates only, but they'll be not too far off I'd say.
