What feature is used to add pass riders and infants to the passenger count?

The feature used to add pass riders and infants to the passenger count is specifically designed to accommodate special cases where those traveling do not require a full fare ticket. Utilizing this feature streamlines the process of counting all individuals on board, ensuring accurate occupancy figures.

Adding pass riders often involves including those who may not have paid for a standard ticket or who are traveling under specific conditions, while infants typically ride for free or at a reduced fare. This dedicated function allows agents to efficiently document these additional passengers without disrupting the primary ticketing system or the standard booking process. This is particularly beneficial for maintaining an accurate passenger manifest for safety and operational purposes.

The other choices do not provide the specific mechanism for counting pass riders and infants in the manner intended. Instead, they focus on broader aspects of ticketing or passenger management, which may not accurately reflect all the specific needs related to counting additional passengers.
