Air Waybill (AWB)

The non-negotiable contract of carriage and receipt of goods for air freight shipments.

Type: Transport Document Region: Global (IATA Standard)

Overview

An example of a standard IATA Air Waybill

An Air Waybill (AWB) is a critical shipping document used for international and domestic air cargo transportation. Issued by the airline or freight forwarder, it serves as a legally binding contract of carriage between the shipper and the carrier.

Unlike a maritime Bill of Lading, an Air Waybill is non-negotiable, meaning it does not transfer ownership (title) of the goods; it simply serves as a receipt and a set of instructions for delivery.

Tracking Number: The AWB number is an 11-digit code (e.g., 014-12345678) used to track the shipment's status in real-time. The first three digits identify the airline (the "airline prefix").

Core Functions

The AWB serves four distinct roles in the logistics chain:

• Contract of Carriage: Outlines the legal terms and conditions of transportation.
• Receipt of Goods: Proof that the carrier has received the cargo in apparent good condition.
• Freight Bill: Often serves as the invoice for freight charges and surcharges.
• Insurance Certificate: In some cases, the AWB can serve as evidence of insurance coverage if requested by the shipper.

Master vs. House Air Waybill

In air freight consolidation, two types of AWBs are used to distinguish between the airline's contract and the freight forwarder's contract.

Feature	Master Air Waybill (MAWB)	House Air Waybill (HAWB)
Issued By	The Airline (Carrier)	The Freight Forwarder (Consolidator)
Issued To	The Freight Forwarder	The Actual Shipper / Exporter
Shipper Listed	Freight Forwarder (at origin)	The actual Exporter
Consignee Listed	Freight Forwarder (at destination)	The actual Importer / Buyer
Purpose	Covers the consolidated shipment of multiple goods.	Covers the specific goods of one customer within the consolidation.

Regulatory & Electronic Requirements

For North American trade, both US and Canadian customs require AWB data to be transmitted electronically prior to arrival.

United States (ACE Air Manifest)

Under the Trade Act of 2002, air carriers must transmit AWB data to CBP via the Automated Commercial Environment (ACE) system.

• Timing: Generally required "wheels up" from nearby foreign locations (North/South America), or 4 hours prior to arrival for long-haul flights.
• Data: Must include Master AWB and House AWB data elements.

Canada (ACI Air)

Carriers must transmit electronic cargo data to the CBSA via Advance Commercial Information (ACI).

• Timing: At least 4 hours prior to arrival at the first port of entry, or at time of departure if the flight duration is less than 4 hours.
• Liability: The carrier is liable for ensuring the AWB data matches the actual cargo on board.

The e-AWB

The Electronic Air Waybill (e-AWB) is the industry standard replacing paper documents. It removes the need for a physical paper AWB to accompany the freight, relying instead on digital data exchange (EDI).

Common Usage Scenarios

Scenario	Application
Time-Sensitive Shipments	Scenario: An electronics manufacturer needs to transport urgently needed components to a factory. Usage: The AWB provides immediate routing instructions and "Special Handling Codes" (e.g., AOG - Aircraft on Ground) to ensure expedited processing.
Perishable Goods	Scenario: A flower exporter in Mexico ships fresh flowers to Canada. Usage: The AWB includes specific handling instructions (e.g., temperature ranges) and ensures the "Perishable" status is visible to ground handlers.
Multimodal Transport	Scenario: Goods move from a US factory to a foreign distribution center. Usage: The AWB covers the air leg of the journey. In "Air-Sea" or "Sea-Air" moves, the AWB acts as the handover document between the trucking/ocean carrier and the airline.
Consolidated Freight	Scenario: A freight forwarder combines small shipments from 10 different clients into one container. Usage: One Master AWB covers the whole container for the airline, while 10 separate House AWBs are issued to the individual clients for tracking and customs.
