The air waybill is the correct document used to identify each shipment by a separate number in air transport. It serves as a contract between the shipper and the carrier, outlining essential details such as the sender and receiver's information, a description of the goods, and specific instructions for handling the shipment. Each air waybill is assigned a unique identifier, allowing for efficient tracking and management of air cargo throughout its journey.

This document is critical in air transportation because it provides proof of acceptance of the cargo by the airline and outlines the terms and conditions of carriage, ensuring accountability and clarity in the shipping process. The unique number associated with the air waybill aids not only in tracking the shipment but also in managing logistics, customs processes, and billing.

In contrast, while a shipping manifest lists all the shipments on a specific flight or voyage, it does not provide a unique identifier for each shipment. A waybill generally refers to a document used for various modes of transport and might not be specific to air transport. A bill of lading is primarily used for sea freight and may not contain the same tracking features relevant to air transport.
