Freight Consolidation & Groupage Explained
How multiple shippers' cargo shares one Master AWB — and why that's the backbone of UAL's neutral-agent model, not just a cost-saving trick.

What groupage actually is, and why it works
Groupage — freight consolidation — is a forwarder combining multiple shippers' individual shipments into one larger booking under a single Master AWB, then issuing each shipper their own House AWB for their specific portion. This is the exact MAWB/HAWB relationship covered in detail on our Master AWB vs House AWB guide — consolidation is what makes that two-tier document structure exist in the first place.
Why it exists commercially: airlines price cargo space in bulk, and a single small shipper rarely has enough volume to negotiate airline-direct rates or fill a pallet efficiently on their own. A forwarder consolidating many shippers' cargo onto one MAWB can negotiate better bulk rates than any individual shipper could alone, and pass a share of that efficiency through — without the smaller shipper needing their own IATA accreditation or carrier relationships.
This is the same neutral-agent positioning already established across UAL's own service: shippers access IATA contract rates and AWB issuance under our accreditation, and consolidated buying power, without holding accreditation themselves. See our CASS settlement guide for how the payment side of that relationship actually clears.
What consolidation changes for a shipper
None of this is a downside of consolidation — it's simply what the structure looks like from the individual shipper's side.
You get a House AWB, not a Master AWB
Your direct contract is the HAWB UAL issues you — see our MAWB vs HAWB guide for exactly how liability differs between the two.
Your cargo may be re-tendered separately if a consolidation is split
If part of a consolidated booking gets offloaded for weight or space reasons, it travels on the next available flight under an amended manifest — covered in detail in the MAWB vs HAWB guide's worked example.
You don't need your own IATA accreditation
Booking through a consolidator's MAWB means you access carrier rates without holding accreditation yourself.
Your rate reflects shared bulk buying power, not your individual volume
A forwarder consolidating many shippers' cargo can negotiate rates no individual small shipper could get alone.
UAL's Neutral-Agent Model
Consolidation is why UAL exists as an intermediary, not just a cost-saving feature
We hold the IATA accreditation, the carrier relationships, and the CASS enrollment — a shipper accessing consolidated bookings through us gets all three without needing any of them directly.

Worked example
Six shippers, one MAWB, six HAWBs
This is the same consolidated KUL–YYZ booking already worked through in detail on our Master AWB vs House AWB guide — six shippers' cargo, one Master AWB, tendered together.
Each of the six shippers gets their own House AWB, referencing the same underlying MAWB UAL holds with the operating carrier. None of the six needed an IATA accreditation, a direct carrier relationship, or enough individual volume to negotiate a bulk rate — the consolidation gave all six access to the same rate UAL negotiated for the full booking.
If the booking gets split in transit — covered in the MAWB vs HAWB guide's own worked example — UAL's obligation runs to each shipper under their individual HAWB, while the carrier's obligation runs to UAL under the one MAWB. Consolidation doesn't complicate that relationship; it's the reason the relationship has two layers in the first place.
What UAL handles for you
We hold the MAWB relationship and consolidated buying power so individual shippers don't have to — issuing your HAWB, settling through CASS, and coordinating re-tender if a consolidation ever gets split in transit.
Frequently asked questions
Not as standard practice — consolidated bookings run on the same flight schedule as any other cargo. Delay risk comes from things like weight-restricted offloads, not from a consolidation deliberately waiting to fill up before it moves.
