jonalwy Welcome to the forum

Of the airlines you list in (6) & (8) only Qantas QF is OneWorld. QR Qatar will join OneWorld on 31 Oct 2013.
Priority services & free lounge access only come with status. Difficult to get flying less than 25K miles
"Good award redemption" eliminates QF (and BA to a point):- high cash YQ fuel surcharges
For mileage collection and low co pay award fees AA is good for many people.

However at this time, in my view, better to get enough miles in one program to get an award or miles upgrade, and then abandon that FFP: you have too many FFP for less than 25K flying miles per year. With small account balances you are at risk of losing the miles due to no activity. Best to stick with 1 OneWorld, 1 StarAlliance airline and/or 1 Skyteam. You can get miles credited to an airline FFP while flying another (partner) airline, subject to rules of your program. Espically the fare class/bucket
