Change term "1K" to something else?
I know this might be sacrilege to some former suUA members, but "1K" is uniquely goofy among airline tier terminology. Not only that, "1K" announced at boarding gates is often taken as the signal for BG1 to surge forward. I'm vaguely aware of its origin as something that would fit in a two-character data field - I think UA could move on from that.
I originally thought "Titanium" might be an idea. I dwelled on it further and decided it wouldn't be a good idea. If "Platinum" gets shortened to "Plat", one can imagine how "Titanium" would be shortened.
I looked up precious metals. Platinum and Rhodium seem to battle for most valuable metal, but "Rhodium" I wouldn't think evokes a sense of value to the average ear.
That leaves Diamond.
I know nothing will change (Kirby would look at cost of changing signs/literature/web/app), but just thinking random thoughts this morning w/ first cuppa...
