Ex-US it is almost always 20-30% higher than QF on the same date/flight. AA is taking advantage of the US gov't requirement for contractors to fly US flagged carriers whenever available, so they have a steady demand for the higher AA fares. Ex-Australia there doesn't seem to be too many US gov't contractors, so their prices match QF instead of commanding a premium. AA does have their yield management fine tuned.
