What a bizarre coincidence....I just got off the phone with Amex and they are willing to cancel my Blue card and move its Credit Limit to an Optima Platinum card. Optima Platinum still has the BVG and many other benefits Blue does not. If you hold a Blue Card you should call Amex and ask to have this done.......a couple comments.....
1) if you have a balance on Blue, they will transfer the remainder of your credit limit only to a new card, then cancel your Blue Card leaving you to pay your Blue balance and issuing you a new card. Example: If you have 4000 credit limit, with a 500 balance they will issue you a new card with a 3500 credit limit and you will still owe 500 on your Blue card which will be closed and you can no longer use.
2) they offered me this with an Optima Platinum card....you will most likely need a low balance, high credit limit, good credit history overall, and an excellent credit history with Amex. (Optima Platinum has no annual fee!)
Try it!!!!! BVG here I come!!!!!
