I have the Chase Marriott card right now, but I was thinking about applying for the SPG AmEx as a hedge for after the merger. I have my doubts whether or not AmEx will be allowed to grandfather people into a Marriott card like Barclaycard did with the AAdvantage Aviator. My hunch is that they will discontinue the card completely or try to sell the portfolio to Chase. I primarily stay at Marriott properties, so it would be nice to have a Marriott AmEx that couldn't be DCCed.
