Logged in to check if recent flight posted and saw this message where usually it tells you how short you are of next MP level: "The elite status tracker will re-appear when the status and benefits of the 2012 MileagePlus program take effect later in the first quarter. Rest assured that your qualifying activity is now counting toward MileagePlus Premier® status for the following year. You can check your qualifying activity balances on the “My Activity” tab below." If this is true (which I doubt) I would love yesterday's miles to fall into 2012! I suspect though that the flight date will trump everything when it comes to posting miles for a given plan year.
