When the American Airlines-Qantas joint venture was first announced I expected that an early route addition would be Dallas Fort-Worth – Brisbane. The head of the Brisbane airport expected it, too, and the CEO of Qantas International predicted their Boeing 787s made the most sense flying Brisbane to LA or Dallas.
Before Qantas began operating an Airbus A380 on the Sydney – Dallas route the flight was on a Boeing 747 and from Dallas to Sydney had to make a stop in Brisbane (but flew non-stop from Sydney to Dallas). Now JonNYC is writing that Dallas Fort-Worth – Brisbane is a route to look for.
