Hi, not sure if this is exactly the right place to pose this question, but no doubt you'll show me the door if it isn't!

I currently have no 'status' with any airlines, although I have been Prem Exec with UA in the past. I have miles in UA, Virgin and AA, in that order. United is my 'preferred' airline because I have more miles with them and they fly to IAD and most other hubs that I need to use.
However, my wife and I have recently started 'FF'ing again and really want to maximise our opportunity.
We are in the UK and flew to LA on business in April, with ANZ as it's a direct flight from LHR and are shortly going to be visiting Hong Kong... probably 3 times total this year. That on its own is going to leave us just short of Prem Exec this year unless I can either justify doing a miles run, or I can persuade UA to upgrade me anyway.
I spoke to the Mileage Plus agent this morning and he just told me flat that there were no challenges on the books... but that may well have been because ANZ have been lousy at passing on my miles for the LA flight... the first flight we've made in the Star Alliance since May last year. At least he took the details and entered them for a missing miles claim.
Any suggestions on a fast track would be much appreciated... including the proper place to post this!
