I had this exact same situation in January with award tickets to St. Lucia. If I logged in as me (GM), it was 35k miles. If I logged out, it was 70k miles. I called the Gold Medallion desk and they would NOT do anything about it, even when I spoke to a supervisor. They refused. So I went on the skymiles ticket and my wife went on the revenue ticket. This really made me angry as I was indeed "traveling" with her.
