I have a Blue Cash with decent AoA. I just got a Starwood since I couldn't PC (Blue Cash has gone down for me since I don't use it as the go-to and get to the $6500 tier anymore). I burned an inquiry for it and that is fine. My question is regarding AoA. If I kept both open, will my Starwood ding my FICO on AAoA for the new account? How about if I closed the Blue Cash and transferred the CL to Starwood, would it report the AoA as the age of my Blue Cash since I've been an Amex customer since say 2002?
