The primary function of an onboard courier service (OBC) is to fly with and monitor a critical item. This service is specifically designed to ensure the safe and secure transport of valuable or urgent goods. An onboard courier accompanies the shipment from its point of origin to its destination, providing a level of oversight and assurance that is not typically available with standard shipping methods. This direct oversight helps to mitigate the risk of loss, damage, or delays, particularly for sensitive items or time-sensitive deliveries.

In contrast, the other options focus on different aspects of transportation and logistics that do not align with the specialized role of an OBC. Transporting passengers with luggage, managing shipping logistics, and handling cargo without supervision are all broader logistical functions that do not provide the one-on-one attention and monitoring of a critical item that an onboard courier specifically offers.
