Well, still no news. While there is still the "review in underway" sticker in the app, I emailed ambassador services to see if they could be appealed to. It will have little effect on my actual status as (1) DIA AMB + Lounge pass = mostly RA, especially with (1) I get enough recognition at my "home hotel" that I feel it won't matter much (2) Japan hotels (where I plan a 20 days trip this year) tend to game the upgrade benefits with 314 types of rooms anyway. It's just that I might have more options for my holiday stays if I am not a upgraded. I'll keep you informed of my fate ;-)
