The first AF has just been posted. I can call to get the card cancelled and get the AF back. Or let it go for another 6 months or so and cancel it. My SO has the same PRG card and I get other cards with the same or better benefits. I still keep my Platinum card.
We'll have the same situation with SPG card later. The new SPG biz card would replace the SPG personal card. We still spend like $3,000 to $5,000 on AmEx cards each month.
Just like to hear some past experience with this situation.
