My husband had a similar situation last week - he was 25 miles away from silver on USAir. After several calls and "no" from supervisors, he gave up. I called the Preferred line regarding my own account, and when I was done, mentioned his situation. The CSR said, "let's see if we can't do something about this." After waiting on hold for a few minutes, she came back and said he was all set. The next day, I checked on-line and he was 1000 miles over the cutoff and it said silver preferred. Don't give up!
