I just spoke to AE and they told me that bonus 5748 for 100k is good thru jan 2012.
bonus 5894 for gold premier 75k is thru july 2011.
I would like to know where I can sign up for the 50k platinum and then apply the bonus.
I tried to get them to issue me the cards on the bonus ID alone, but they said without the rzsvp # it won't work.
