2010 (current) status: Premier (lite - needed DEQM and a short MR to soft land from 1P to 2P)
2011 projected status: Premier (25.5k EQM)
2010 spend: ~$1,500
Did your status affect your spend: (yes/no): Not particularly.
I have a bit of a weird situation - earned 2P entirely on the basis of one promotion (Denver Deal of the Decade). Flew a W class to LON, which earned me a free international ticket. I don't think the free ticket was supposed to earn miles, but mine (to NRT) did earn EQM and RDM.
In any case, I've flown UA a fair bit this year, but almost entirely in XY (only 3 paid segments, other than the two flights above!). Pretty glad I ended up right above the line for keeping 2P (and E+).
