So on Monday I finally made Platinum (through a status fast track) after hitting EQM/EQD requirements. So I changed seats to the complimentary MCE seats on 1 of 2 flights for tomorrow during the week, and was added to the upgrade list for one of my segments that's less than 500 at T-48.
I logged on tonight and noticed some MCE seats in the bulkhead were open that I wanted compared to where I was at (5C) and tried to take it, but kept getting an error. When I hit my AA account, I noticed that ~2500 EQMs and ~200 EQDs were no longer there, dropping me back to Gold. I could no longer select an MCE seat until I was T-24 (finally was able to select it right when I hit T-24). Still shows Plat, but my plat benefits don't seem to be there anymore.
Why would EQMs and EQDs all of a sudden disappear from my account?
