There is another way if you are just thinking of using your points for travel on American, rather than to try and convert to AAdvantage miles for other partner travel, etc. MR recently introduced a way for members to use their points for flights on virtually any airline you choose. From my understanding (i have actually yet to use the option) you use a link from American Express Travel Services to search for the flight you need and when the payment page comes up, choose to redeem your MR points for all or part of the price of the ticket. Because you are effectively channeling points/miles into money, you can possibly assign a value per miles/point into the purchase price and go from there. Of course the positive thing about this is that you control searching for the flight and price of the ticket you are looking to exchange your points for. Here's where you can start your flight search:

Hope this helps.
