If you work in shipping, logistics, or international trade, you've likely encountered both Air Waybills (AWB) and Bills of Lading (BOL). While they might seem similar at first glance, these documents serve distinct purposes and aren't interchangeable. Understanding their differences is crucial for proper shipping documentation and smooth logistics operations.
What is an Air Waybill (AWB)?
An Air Waybill (AWB), also known as an air consignment note, is a document issued by an airline or carrier that accompanies goods shipped by air freight. It serves multiple important functions:
Transportation contract between the shipper and carrier
Receipt of goods acknowledging that the carrier has received the shipment
Tracking document with a unique number for monitoring shipments
Shipping instructions for handling and delivery
Unlike some shipping documents, an AWB is non-negotiable, meaning it doesn't represent title to the goods, and the shipment must be delivered to the specific consignee named in the document .
Key takeaway: An AWB is essential for air freight but doesn't prove ownership of the goods being shipped.
What is a Bill of Lading (BOL)?
A Bill of Lading (BOL or B/L) is a legal document issued by a carrier to a shipper for various transport modes, primarily ocean shipping but also truck and rail transport. It serves three critical functions:
Receipt for goods confirming what was tendered to the carrier
Evidence of contract of carriage outlining shipment terms
Document of title representing ownership of the goods in some cases
The BOL is typically negotiable, meaning it can be bought, sold, or traded while goods are in transit, and the holder has the right to claim the goods .
Key takeaway: A BOL is crucial for sea freight and represents both a transport contract and potential ownership of goods.

When to Use Each Document
Choose AWB for:
Time-sensitive shipments requiring fast delivery
High-value items where security and speed are priorities
Smaller volumes that don't require container-level loading
International shipments where air freight is most practical
Choose BOL for:
Ocean freight of any kind
Large volume shipments requiring full containers
Situations requiring trade financing (since BOL represents ownership)
When transferring ownership of goods during transit is necessary
Why the Distinction Matters in Logistics
Understanding whether you need an AWB or BOL prevents costly delays and complications in your supply chain. Using the wrong document can lead to:
Customs clearance issues at destination ports
Delivery refusals if proper documentation isn't presented
Legal complications in case of loss or damage claims
Payment delays for international transactions

Common Questions Answered
Can I use an AWB for sea freight?
No, AWBs are exclusively for air freight. Ocean shipments require a Bill of Lading .
Is an AWB number the same as a tracking number?
Yes, the unique AWB number serves as your primary tracking reference for air shipments .
Why is the BOL more complex than the AWB?
The BOL's additional complexity stems from its role as a negotiable document of title, which requires more detailed information and safeguards .
Conclusion: Key Takeaway for Shippers
While both AWB and BOL are essential transport documents, they serve different purposes and aren't interchangeable. Remember: AWB for air freight, BOL for ocean, rail and truck shipments. The critical distinction lies in the document of title function-BOL represents ownership and is negotiable, while AWB does not.
