Amex has so far refused to double my points even though I am one of their better customers. Have been using Explorer/Edge combo. If I do not get the doubling, am planning to transfer to KF but I will struggle to efficiently use my KF points prior to expiry within 4 years. The only way way to avoid point expiry is to get KF status - but that would require actually paying money for flying - something not may AFF readers are fond of...
In desperation, I decided to apply for a Centurion card, hoping that if this is granted, they may be kinder to me, even though I well and truly missed the cutoff date. About 2 weeks after asking Amex to consider giving me a Centurion - they formally offered me this Card.
I explained that I would only consider this if they doubled my points. 3 days later - a negative response! No point doubling, but instead, they will not charge me the $5k joining fee, "only" the usual $5k yearly fee (which I can make deductible).
I have read elsewhere that customers need to wait for an invitation for Centurion, but clearly, this is not accurate as I was only offered the card because I asked the question.
I have not decided whether to take up the Centurion offer. Although I am very disappointed that my current points will not be doubled (not much logic to this), Centurion will have the best earn rate although this is somewhat marginal versus the Platinum card. I have read mixed reports about the value of this card and many of the benefits they have listed for me, such as the access to a Relationship Manager ( ? largely a travel agent) are of little use to me - I have not had pay for an international flight for over 10 years.
