This is a combination-lack-of-knowledge question, so may be slightly OT, but not completely. I've had a personal SPG account since May, and want to reset my 12-month clock and close it. (I have SPG Biz, don't worry
). I don't want to lose the CL, so I can downgrade to the Blue, or shift to my Delta Gold card. I also bought a GPS on the card,and I want to retain the AmEx extended warranty. Does either option allow me to hold on to the protection? Does the Blue option keep the same account number, and thereby it's the same account?
Thanks.
