Your call if you think it's worth it to do 800K. I'm at 910K myself, booked to 940K or so, and will stick it out to 1MM. After that, AA will look quite good, or at the very least doing as much non-UA *A metal as I can.
I see you have flown over 2.2MM miles on United. As you received benefits and entitlements above and beyond what you paid for our billing department will be contactingo you shortly to arrange a repayment plan for you. Rest assured we have enhranced the Mileage Plus plan going forward and any benefits you receive from today onward shall be complimentary and will remain complimentary at our own discretion until such time as we see fit to retroactively bill you for those benefits. Thank you for being such a loyal customer of United.
As others have said its just BIS miles counting towards MM statuses these days.
I really love good CS. But then again, don't we all?
