Somewhat confusing answer. It will "flow" to open time (meaning the trip was dropped from the pilot's schedule) if a personal drop is approved, which means the reserve availability was sufficient to grant the PD.

It will become a "Q" trip listed in open time, because the PD is disapproved, due to lack of reserve availability.

Also, it doesn't run "around the same times as PCS." It IS part of the PCS run.

In this world, precise language matters.
