Air Waybill (AWB)

An Air Waybill (AWB) is the primary transport document for air freight shipments. It serves simultaneously as a shipping contract between the shipper and the airline, a receipt for the cargo, and a customs declaration document. Every commercial air freight shipment worldwide travels under an AWB.

Structure of an Air Waybill

The standard IATA air waybill is an 11-digit number: the first three digits are the airline prefix (e.g., 020 for Lufthansa, 057 for DHL, 083 for FedEx), followed by an 8-digit serial number. This number is the universal reference for tracking a shipment from origin to destination.

The AWB document itself contains:

• Airport of departure and destination (3-letter IATA codes)
• Shipper and consignee details
• Description of goods, weight, and dimensions
• Number of pieces and packaging type
• Declared value for carriage and customs
• Handling instructions (e.g., "keep refrigerated," "this side up")
• Charges — freight, fuel surcharge, handling fees
• Special service requests (e.g., dangerous goods declaration)

Master AWB vs. House AWB

Master AWB (MAWB): Issued by the airline to the freight forwarder. Covers the entire consolidated shipment from the forwarder to the airline.

House AWB (HAWB): Issued by the freight forwarder to individual shippers whose cargo is consolidated under the MAWB. The HAWB is what the shipper receives and uses for tracking.

AWB vs. Bill of Lading

In ocean freight, the Bill of Lading (B/L) is a document of title — it can be negotiated and transferred to release cargo. An Air Waybill is non-negotiable: it names a specific consignee, and only that consignee (or their authorized agent) can collect the goods. This non-negotiable nature makes it unsuitable for letter-of-credit transactions that require a negotiable document, though some banks accept AWBs for certain trade finance structures.

Electronic Air Waybills (e-AWB)

IATA launched the e-AWB initiative in 2010, and today more than 75% of international air freight moves under paperless e-AWB. The e-AWB replaces the physical paper document with electronic messages transmitted between shipper, forwarder, and airline systems. It reduces errors, speeds up processing, and is now mandatory on many major trade lanes.

When tracking a shipment, the AWB number is the primary reference across all airline and forwarder systems.
