The current American Airlines promotion offers up to 100% bonus miles.
Here are the latest offered deals:
- Buy 2,000 to 9,000 AAdvantage miles and receive 50% bonus miles
- Buy 10,000 to 49,000 AAdvantage miles and receive 70% bonus miles
- Buy 50,000 to 149,000 AAdvantage miles and receive 80% bonus miles

You can redeem AAdvantage miles on any other Oneworld airline. This includes Qantas, Cathay Pacific, Finnair and Qatar Airways, and partner airlines of AA.
The minimum purchase is 2,000 miles. Let's do some maths:
Qantas First Class between Australia and Asia cost 50,000 miles one-way (incl Sydney-Hong Kong)
If you were to purchase the maximum miles, you would receive 300,000 AAdvantage miles (including 150,000 bonus miles) for a cost of USD4,794.50.
So that's 6 first class tickets to Hong Kong. Or whatever else you wanted to spend it on.
