well, to update, I finally got it resolved yesterday with a much better infirmed and very helpful agent over the phone.
My ticket was a revenue econ then voucher upgrade to UC and only paying the extra taxes
then I used the second voucher as a companion ticket paying only UC taxes. end result my total outlay was over a thousand dollars less than last weeks "this is the best deal" cr@p
i then used the savings to book the Retreat Suite making Mrs FB very happy and winning some severe brownie points.
