I'm probably stating the very obvious, but just like the flow at ENV/PSA/PDT, shouldn't the CPP only be thought of as another tool to move on, vs a golden guaranteed ticket to UAL (which it obviously is not)?
I'd absolutely participate in the CPP, butttttt I'd ALSO have my apps out to ALL the legacies and most of the LCC's/ACMI's, and update them early, hard and often! Not to mention other things like networking like crazy, and hitting the job fair circuit, etc.
