I was recently awarded Premex status. I simply FAXed a letter explaining to UA that my flight patterns had changed, including my 1999 membership cards for Alaska and Northwest, along with copies of my most recent statements.
I think the trick is that they will award Premex only to folks who have equivalent status on another airline.
Sorry, meant to say that you call your letter "Go for the Gold." I have the fax number somewhere. If you want it call United or e-mail me.
