Convert your Starwood Preferred Guest Starpoints to American Airlines AAdvantage miles and earn a 20% bonus from August 1 – September 14, 2016. Plus, if you convert 20,000 points in one transaction, Starwood automatically adds a 5,000 bonus, that’s a standard offer.

Example

• Your 20,000 Starpoints convert to 20,000 AAdvantage miles (20,000 miles total)
• When you convert 20,000 points, Starwood adds a 5,000 point bonus (25,000 miles total)
• You earn 20% bonus miles on your conversion (20% of 25,000 = 5,000; 30,000 miles total)

SPG points are some of the most valuable out there and I have never converted them to AA miles. But with this bonus it does make more sense. The transfer takes about 2-3 days.
