You need to see a GA or Sky Club Agent to get it done. I assume the kiosks will work for seat changes however but have never tried.
Most of HNL-mainland flights are an overnight connection. Thus SDC doesn't work since the connection is a different day. Always has involved an agent AFAIK for these type of connections.
