Read through the entire thread. I have mixed feelings on this, I'm 1P right now on status match, will likely make 1K on miles next year, and this feels like a slap to the face; US Airways did this a few years ago and greatly ticked off their elite base. Nice to see UA making the same damn mistakes ...
As I have limited vested interest in staying with UA, I'm eyeing this very carefully; if this is the only major devaluation of MP, its tolerable. If E+ goes, I'l history; I'll go to US, and fly UA as *G on TPAC.
Won't go back to Delta, and can't go to AA easily.
