as your nickname indicates, DFW
is oneworld, as AA
is, and so DFW
is a oneworld hub. It would provide perfect connections between nearly every major city in the US (east and south of the US in particular) and Sydney with only one stop at DFW
It's just speculation, of course, and the probability of actually seeing a Qantas A380 @ DFW
is quite low, but it's possible and would make sense.
And, well, since the distance is 7454 nm according to the great circle mapper, we'll probably have to wait for the IGW version
