American Airlines are doing up to 75000 bonus points when you buy points.
You can purchase anywhere up to 200,000 points for US$3687.
Using those points, you can book cheap international trips.
e.g. it's 72,000 points one way to New York first class. Which means you can fly to NYC first class return for US$2600.
Use https://www.americanairlines.com.au/reservation/awardFlightS… to find available flights. You can put a flight "On hold" for up to 4 days until you buy the points.
I thought AA was only 100,000 points a year that you could buy??
