Just out of interest: what kinds of AA awards are people generally targeting when they buy points? (This might spur a new thread...)
For US DM, most of us had an easy "sweet spot" for awards: 150k for a AUS/EUR award in F, or 140k for a AUS/USA award in F, or 120k and 110k respectively for the J equivalents.
Are people similarly targeting similar amounts for AA awards? So in the case of AUS/EUR (e.g. to LHR) award in F, that would be 160k AAdvantage miles, which, for those who have gone from a standing start, this promo and the last one would be insufficient to cover. Also, rationalising, it costs AUD 3600 for 90k + 75k = 165k points and not hit the goal yet. AUD 4000 is still cheaper than any advertised F return fare, but suffice to say it relies on one actually wanting to spend that much for a ticket in the first place.
For AUS/USA (which is quite difficult to get), it would be 145k return in F. If you can't get a direct across the Pacific, you may have to go via Asia. I'm not sure of the mechanics of redeeming with AA, but at worst you'd be paying for two awards (AUS/Asia and Asia/USA) which would cost a total over 200k wholly in F.
In J all those totals drop to quite more modest values which is very much achievable with these two recent promos.
The other alternative is to do one-ways rather than return journeys, finding an economical way to get back (e.g. cheaper return fares outside Australia back to Australia, or LifeMiles redemption).
It should be noted carefully that in general (at least from what I can read from the AA forum on FlyerTalk) stopovers are not allowed at all on any given itinerary (unlike US DM, which allows one hub stop), and routing must be generally as direct as possible.
In the older days, there were really, really good value (cheap!) "RTW" style AA awards available. The "RTW" awards with AA are still good value for the mileage paid, but they are usually well beyond the scope of the two recent promos (and start to push on the boundaries of whether it's actually better just to purchase the cash RTW fare instead, which has far less restrictions).
My idea of redeeming with AA was mostly to do some one-way journeys on routes which are on my "list", e.g. CX F, BA F ex-LHR, BA CW LCY ex-JFK.
