Based on last year's (free) Amex HHonors card spending. Once again they are renewing for two years. Old card that I just cut up tonight, based on 2010 spending, was good through 3/13. New one, based on 2011 spend, is good through 3/14. Yes, 2014 - the Mayans would be shocked! There has been talk of this two-year practice on this Forum before. It's not technically what I read the rules to say, but it is what happens nonetheless. And there has also been talk of "closing the loophole," but obviously as of today's mail it is still loopy. If I can get enough places where I have used Master Card to take my new Hilton Amex "Surpass," I may well be "Diamond" a year from now, but if not, it's nice to know my "Gold" doesn't expire for almost 26 months.
