DL to DL bag policy is over 6 hours you can short check, over 12 you must short check.. This only applies when checking bags in with DL and only for DL to DL connection. (DL system imposes the limits)
However an agent who knows how can override 12 hour limit. They just add the segment onto the bag tag like it was a separate ticket.
