Yes, I do understand that Life Time Diamond is exactly that - life time Diamond for life.
Perhaps I wasn't clear in my original post. I would have been on-track to make Diamond again this year the hard way - on stays, nights and spend. However, when I check in, my status shows as Diamond (not LTD) and what I would like to see, perhaps wishful thinking, is my LTD designation to be displayed instead when checking in. I can count on one hand the amount of upgrades I have received as a Diamond for the past 5 years (been Diamond for the last 25 years). Just maybe, having LTD designation shown may increase my chance of an upgrade.
Please don't get me wrong, I'm thrilled to have made LTD as I plan to retire in 3 years. I would like to think that LTD brings additional benefits (perhaps a tier above Diamond), but this is yet to be seen.
