I am one of them (100 percenters) and recently I have had success getting the agents to manually upgrade when I was missed by the EUA. This does not mean that I like this system better than the last, where I felt (rightly or wrongly) that I had some control of my situation and knew exactly what I could do at all times.
I think that cwpfly has some extrememly valid points and his idea of a "fix" is a very good one, but I would make one suggestion that might help him out and that is "always travel on separate records." I also travel most of the time with another Platinum, and the extra margin provided by separate records comes in when the EUA misses one of you. In that case, there has never been in our experience the agent who did not upgrade the other Platinum instantly and without further ado.
