Not quite right. Standby shifts are contractually considered flight assignments. Flight assignments are considered in order and then Rap proffers. If you proffer for trips, then standby, then rap they will be awarded in that order. If you proffer trips, raps, standbys the standby will go ahead of the rap. Only raps and standbys the standbys will be considered before raps. A standby will not, however, jump up over another flight assignment proffered for.
