Thank you. For this initiative, the goal is purely to maximize AA points. I agree, the Amex Platinum would be best overall but from what I understand you cannot transfer membership rewards points to American.

...As an aside, I need to figure out the best way to maximize an American Express bonus, next year, after American Airlines goal achieved. I've been an Amex gold card holder for 30+ years, and need to figure out if there is an upgrade path, or I need to cancel gold outright to get something like a 100K bonus.
