One settlement system, not one invoice per carrier
CASS — the Cargo Accounts Settlement System — is an IATA-administered clearing system between IATA-accredited cargo agents and participating airlines. Instead of an agent settling separately with every carrier it books cargo through, CASS consolidates those charges into a single periodic settlement, on a standard twice-monthly cycle.
Mechanically: an agent issues Air Waybills under its own IATA code across however many carriers it works with. Each carrier reports its charges into CASS rather than invoicing the agent directly. IATA consolidates those charges per agent, and the agent settles once per cycle — not once per airline it happened to book with that month.
UAL holds a single IATA Cargo Agent accreditation, based in Halifax — Kuala Lumpur is our operational origin-side office, built through our family's 35-year United Travels operation, not a second, separately accredited entity. Every AWB we issue, regardless of which carrier operates the flight or which end of the corridor it originates from, settles through that one Halifax accreditation and its CASS enrollment.
UAL's Accreditation, Precisely
One IATA accreditation, based in Halifax — not two
UAL holds a single IATA Cargo Agent accreditation, headquartered in Halifax. Kuala Lumpur is our operational origin-side office — not a second, separately accredited entity. Every AWB settles through the same Halifax accreditation and CASS enrollment, regardless of which end of the corridor it originates from.

Worked example
A House AWB settling through CASS
Take a consolidated shipment referencing the MAWB/HAWB relationship covered on our Master AWB vs House AWB guide — the carrier invoices UAL, not the individual shipper, and that invoice settles through CASS.
UAL issues the HAWB to the shipper and holds the MAWB relationship with the operating carrier. The carrier's charges for that MAWB — and every other MAWB UAL issued that cycle, across every carrier we work with — are reported into CASS rather than invoiced to us individually by each airline.
Twice a month, CASS consolidates those charges into one settlement. UAL pays that single amount rather than reconciling a separate invoice from each carrier on our contract list individually — the same carriers referenced when we quote a lane in the first place.
What UAL handles for you
Every AWB we issue settles through our own CASS enrollment — you never see a separate airline invoice or need your own IATA accreditation to book through us.
