Air Waybill (AWB)
The complete guide: MAWB vs. HAWB, all 18 AWB fields explained, e-AWB, difference to B/L, tracking and the process in 7 steps.


What is an Air Waybill (AWB)?
The Air Waybill (AWB) is the central transport and legal document in air freight. Standardised by IATA and valid worldwide. The AWB simultaneously fulfils three functions:
Contract of carriage
Binding contract between shipper and air carrier
Receipt
Confirmation of cargo receipt by the carrier
Tracking document
Unique 11-digit number for worldwide real-time tracking
Important: AWB is non-negotiable
Unlike the Bill of Lading (sea freight), the AWB is not a document of title. The consignee does not need to present an original – they simply identify with ID and AWB number at the destination airport.
MAWB vs. HAWB – The two AWB types
Master Air Waybill
Airline → Freight Forwarder
Covers the entire consolidation. Contains flight details, total weight, airline routing. Shipper normally does not see this document.
House Air Waybill
Freight Forwarder → Shipper/Consignee
Contains individual shipment details of the specific shipper. This is the document that shippers and consignees receive and use for tracking.
For direct bookings (shipper books directly with the airline, without forwarder) there is only one MAWB. The shipper is then also the shipper in the MAWB.

e-AWB – The Paperless Air Waybill
The e-AWB (Electronic Air Waybill) is based on IATA Resolution 672 and eliminates the need for physical paper documents. The adoption rate exceeded 80% globally in 2023; e-AWB is now de facto standard on most main routes (IATA target: 100%).
e-AWB Benefits
- Faster processing (no paper documents)
- Fewer errors via automated data validation
- Free – no printing, no shipping
- Environmentally friendly
- Real-time data availability for all parties
Limitations
- Not all countries accept e-AWB (e.g. certain Asia/Africa destinations)
- Special Cargo Community Systems (CCS) required
- Dangerous goods shipments still require paper documentation
