The rules require your original fare class needs to be available to do this but generally (however not always) this is true for most fare classes on day of travel. 12 hours are so prior to the HNL flight, the displaced waitlist should given you a rough idea of where you might stand (remembering a few more folks will be added to the waitlist as they checkin later).
