However, I think Qantas would be smart to operate the Sydney-Dallas flight because given that both Qantas and American Airlines are OneWorld members, American Airlines can put a codeshare flight number on this flight and because of plentiful capacity at DFW, Qantas can feed the main hub for American Airlines' massive USA network. It also gives the option of another route from Sydney to London, where AA 777-200ER's using that new International terminal at DFW can fly passengers to London that arrived from that Qantas flight from Sydney to Dallas.

SYD-LHR via DFW would not be a very attractive service.

There are dozens of more direct connection oppertunities to London in Asia.
