This started May 15th and I seemed to have missed it but there is a 20% transfer bonus offer for Canadian RBC Avion Platinum and Infinite cardholders to transfer their Avion to American Aadvantage miles, until June 30, 2013.
The minimum transfer amount is 5,000 and after that in 100 point increments.

Generally I convert all my RBC Avion into AA because I have enough BA from AMEX CA MR conversions, so I love it when RBC runs these promotions.

You can call 1-800-769-2512 to transfer your points. Here is the website you want to check if I have missed anything about this promo.
