Yes. This is one of those instances where AA/Citi has out smarted themselves. You either are an AC member with a card that is recognized as such or your not. Having to explain/educate/argue should not be our problem for $450. So far, when I cross the next MM threshold which should happen before the end of my first year, I see no reason whatsoever to keep this in addition to my Amex Platinum.
That's good, you should have less of a problem at the SEA Board Room. Some of the cards with chips seem to not have the logo anymore.
