It has been confirmed by FICO that sub-prime and prime CCs are weighted equally, one is not scored better than the other. This policy will continue with the new FICO scoring model that takes effect this September.
I see there was recently talk of converting or upgrading AMEX Delta Skymiles to AMEX BLUE CASH. I did that and it worked like a charm--no credit pulled, no new account numbers.
I am wondering--can I upgrade any of my other cards--I have a CITI AMEX AAdvantage card, an Orchard Bank Card and a Capital One card.
It worked with AMEX, maybe it'll work with others? Also while we're on that subject, can someone explain how having a prime credit card on a report is more helpful to your FICO then having a subprime card?
