So your suggested plan put a bit of space between the cards I outlined. I can't go for the CSP/CSR double dip because I already have a CSP card (over 24 months but I don't think they will issue me another one, will they?) My plan is not to leave chase but to accumulate as many URs as possible. If I do go with AMEX it will put my spend in Membership Rewards which I don't have many, but could help in transferring them to an airline, which I could be doing with my URs to United for a future trip.
I modified my dates for applications but I DO NOT want to get shut down. If I get a denial I'll modify those dates further, I guess.
Anyone have all of these Chase business cards, both players? Is it unusual to have all of these Chase cards within 2-3 years?
