I think this shows when UA hasn't been assigned a gate for their flight. The State of Hawaii controls the gates and makes the assignments. If they haven't done it yet, UA has nothing to report, therefore PAD is what they advertise as the gate. I had this happen recently as well, but as the time drew closer to the flight, it was updated.
Thanks. Strange change in practice.
