I am a dBlack (78,000 miles flown in 2013 - most of my flights have been on United) member of Aeroplan and have been living in the US for the last 18 months. I would like know how to obtain Platinum status on MileagePlus and give up my status with Aeroplan, so that I can obtain the benefits of MileagePlus Platinum.

In addition, I have over 420,000 Aeroplan miles that I would like to transfer into MileagePlus.

Can both of these be done via Star Alliance or Aeroplan or MileagePlus or a combination of both? I was speaking to a MileagePlus rep who was not helpful at all in this regard.

I would really appreciate any support or guidance on this item. Thanks in advance.
