An On Board Courier or OBC is a courier who accompanies fast and time-critical shipments personally and delivers them to the recipient in person. On Board Couriers deliver urgently needed spare parts, important documents and medicinal technology, but also the designer dress for the fashion show as fast as possible and with the highest possible security from A to B.When, for example, a plane has broken down in Abu Dhabi because a small, but critical part is damaged, the important spare part must be delivered as fast as possible. A grounded airplane is causing high costs and a lot of inconvenience. This is where the OBC comes in: He picks up the spare part directly at the producer or the warehouse and takes it with the fastest flight connection to its destination.
