If you want to upgrade with an AA instrument you cannot do as AA does not fly to Australia (but codeshares on QF). Via Asia you may have a small chance of an upgrade, but you have to get to an airport that AA flys from. If you have AA miles look for an award on QF or one of non OW AA partners.

Lounge access will be as per your AA (OW) status if applicable
