I like those odds. Much appreciated. It turns out that one gets 20% of the membership reward points returned and $200/yr from AMEX good for incidentals (e.g., change fee), if one uses an eligible card and books through their services:

When you incur incidental fees while traveling with the airline you selected, you can receive statement credits for the charges that appear on your Business PlatinumŽ Card for up to $200 a year. Please allow 2-4 weeks after the transaction for statement credits to appear on your account.

Your enrollment will remain in effect for the Card and airline you selected for the 2010 and 2011 calendar years. You will have an opportunity to change your airline selection for the 2012 calendar year at the end of 2011. No action is needed if you wish to maintain your current selection for 2012.
