The Air Waybill (AWB) is a document that accompanies an airfreight shipment. The AWB is a contract between the sender and the airline transporting the shipment. The AWB is also evidence for the transport contract and for the delivery of the goods. A transport via On Board Courier does not require an AWB, as the goods transported are declared as luggage rather than airfreight.
In the Air Waybill you find the shipping list containing all accompanying papers for the transported airfreight:
Without an Air Waybill goods cannot be shipped as airfreight. For the emergency logistic it is therefore very important that an AWB be issued, otherwise the timeline cannot be met. The exception: a transport with an On Board Courier doesn’t need an AWB, because your shipment will be handled as luggage, not as air freight.
