My dad downgraded his Surpass to free Hilton card a little before Ascend was introduced (about 2 yrs ago), and he’s yet to receive any upgrade offers. The strange thing is that he still gets emails from Hilton (not AMEX) telling him of the benefits of *his* Ascend card (which he’s never had). Hilton must not have been notified that he downgraded his card, hence no offers. Conversely, my wife, my mom and I have all gotten upgrade offers and we’ve all downgraded from Surpass.
