An inflight entertainment system and method for use therein reduce the loading time required to preload programs identified in playlists onto seat end equipment. Loading time is reduced by retaining programs included in playlists on seat end equipment across flights and making incremental updates to such programs to account for changes in playlists, rather than updating them wholesale for each flight. Loading time is further reduced by adding programs to seat end equipment for the current flight, where possible, by copying such programs from other seat end equipment, rather than copying them from head end equipment.
