This is a significant factor that ONLY AMEX provides, this backdating benefit. If, for example you apply for additional AMEX cards, your MONTH of membership will be whatever month you apply in, but your YEAR of membership backdates to the 2005 membership date that you are now showing. So, theoretically, depending on what MONTH your current card shows, you could backdate to a date prior to that! IF for example your current membership date is 10/2005, and you apply for and get a new AMEX card this month, your membership date will show 02/2005, 8 months PRIOR to your original card! THAT, my friend, is the benefit of backdating from AMEX and the affect it has on your AAofA.
