And the minor point that the QF AOC permits aerial work, charter, and RPT. QF also has their own travel agency.
Your thinking is along similar lines as CASA. Whether QF holds an AOC authorising RPT services is irrelevant. The Qantas flight over Antarctica can not be RPT and must therefore be classified as air charter. CASA's policy in the past, predicated on their incorrect interpretation of CAR206, has been that individual seats on an air charter service can not be sold via an interposed entity. The AAT decision now determins that individual seats may be sold on an air charter, via an interposed entity, where there is a common interest amongst those travelling.
