Logic would be if you're a lifetime diamond you are also > lifetime plat....but I'd be surprised if on Jan 1 or Feb 1 or whatever date it is each year Delta deposit both plat and diamond CBs for a lifetime diamond. My guess is they'll deposit diamond CBs and then in a few years change it up to say if you're a lifetime diamond but not flying the same as an annual actual diamond, the CBs will dissipate too.
