The air waybill or air freight bill of lading is the most important document issued by a carrier either directly or through its authorized agent. It is a non-negotiable transport document, that covers transport of cargo from airport to airport. By accepting a shipment, an IATA cargo agent is acting on behalf of the carrier whose air waybill is issued.
Air waybills have eleven digit numbers which can be used to make bookings, check the status of delivery, and current position of the shipment.
Air waybills are issued in 8 sets of different colors. The first three copies are classified as originals. The first original, green in color, is the Issuing Carrier's copy. The second, colored pink, is the Consignee's Copy. The third, colored blue, is the Shipper's copy. A fourth brown copy acts as the Delivery Receipt, or proof of delivery. The other three copies are white.
