That would be me significantly shuffling around my Amex card "portfolio" (cancelled the Business Platinum, switched to a personal GRP and SkyMiles, new HH, etc) as well as applying for the Chairman Card while out of the country for several months.

So not really a card replacement, just me being unable to get the initial cards easily! (I did ask Amex if they could bundle multiple cards together to reduce the hassle on both ends, but they couldn't.)
