I'm not exactly sure I understand what you're asking. In order to roll ANY miles over to 2011, first you have to hit 25K this year, then anything over 25K will roll over to next year.

As far as purchasing something to get 2K MQM's, I don't think it's cheap, and as tomorrow is Dec 31, whatever activity you may do to get the MQM's, they may not post til after Jan 1.

A quote from DL.com:
" . . . . any MQMs earned above your Medallion qualification level at the end of the year will automatically roll over to your MQM balance for status qualification the following year. Whether you roll over 500 miles or one million, there’s no limit."
