Never checked availability and never had problems. They few times I didn't get an upgrade was when other flights were delayed and PAX thrown on my flight (or me thrown on another flight)
The last experience I had with Copa in UIO was that the GA was not at all attentive to the UG process. When I inquired about it, he said "1st class is full" when in fact there were only two seats taken. The GA @ LAX was equally disinterested. This was a couple of years ago, so perhaps things have improved since.
