A ticket issued with the wrong fare, an incorrectly calculated tax, or a booking left active after a ticket is voided can expose a travel agency to costs that extend well beyond the original transaction. For travel agencies, financial risk doesn’t end when a passenger receives an electronic ticket. Airlines continue to audit bookings, ticket issues, exchanges and refunds, with discrepancies potentially resulting in Agency Debit Memos (ADMs).

An ADM is an accounting instrument airlines use to recover adjustments arising from electronic tickets and refunds processed by travel agents. Under the International Air Transport Association’s (IATA) Billing and Settlement Plan (BSP), the memo is issued through BSPlink and, once its lifecycle is completed, becomes part of the agency’s outstanding amount due on its BSP remittance date.
IATA’s BSP Manual for Agents, effective September 2024, identifies ADMs as a formal part of the airline-agent settlement framework. The manual also requires agencies to monitor BSPlink regularly because debit memos and related communications are made available through the platform.
The potential exposure is wider than incorrect ticket pricing. Fare under-collection, missing or incorrectly collected taxes, commission errors, incorrect refund calculations, unauthorised card transactions and failure to comply with airline-specific fare conditions can all lead to financial adjustments.
Kenya Airways provides a practical illustration of how these rules translate into agency costs. Its published ADM policy, updated in June 2023, identifies a range of violations and associated recovery charges. These include a US$50 charge for certain missing or incorrect contractual ticket information, US$50 per segment per passenger for incorrectly booked special service requests, and a US$100 charge per passenger for duplicate passenger name records.
The same policy identifies speculative bookings, repeated cancellations and rebookings, incorrect ticket plating, uncollected taxes and misuse of fare conditions among practices that can trigger debit memos. It also provides for recovery of fare differences and additional charges in specified circumstances.
The figures are specific to Kenya Airways’ published policy and should not be mistaken for standard charges across all airlines. IATA advises agencies to consult each carrier’s ADM policy because the circumstances and administrative fees differ between airlines and can also vary by market.
The cost of getting voids and refunds wrong
Voiding and refunding are two areas where timing and procedural accuracy matter.
According to the IATA BSP Manual, agents can void tickets through their ticketing system provider or global distribution system on the same day they are issued, up to midnight. A ticket that falls outside the applicable voiding window generally has to be handled through the relevant refund process, subject to the airline’s rules.
Refunds are not simply the reversal of a payment. The agent must follow the airline’s instructions, use the same form of payment as the original transaction and ensure that the refund is calculated according to the applicable fare conditions. The BSP manual also states that an agent cannot refund a transaction issued by another agency.
There is also a direct effect on agency earnings. Where a ticket is refunded, any commission claimed on the original transaction must ordinarily be returned to the issuing airline, unless the carrier specifies otherwise.
Errors in processing refunds can therefore create additional reconciliation work, delay the return of money to customers and expose agencies to further adjustments. Where an agency is uncertain about the correct refund calculation, IATA provides for the use of a BSPlink Refund Application, through which the airline can review, amend or reject the request.
The importance of disputing an ADM
Receiving a debit memo does not necessarily mean that an agency must accept the amount without question. IATA provides a formal dispute process through BSPlink.
Under the September 2024 BSP Manual, an agency has a 15-day period from the date an ADM is issued to register a pre-billing dispute. The airline then has 60 days to accept or reject the dispute, or adjust the amount. If the matter remains unresolved after the ADM has entered billing, an agency may still raise a post-billing dispute within 12 months of the transaction date, subject to the prescribed requirements.
However, a post-billing dispute does not automatically suspend payment. The manual states that the agency must remit the full billed amount, including the disputed amount, while IATA holds the disputed sum in escrow for 30 days to allow the parties to resolve the matter.
This makes record-keeping particularly important. Ticketing records, fare calculations, passenger communications, payment authorisations, airline correspondence and evidence of changes or cancellations can determine whether an agency is able to substantiate its position.
Ticketing compliance is a business-control issue
The risks extend beyond the ticketing desk. Kenya Airways’ published booking policy applies to bookings made through GDS platforms and direct connections, including reservations that are never ultimately ticketed. It prohibits practices such as duplicate bookings, speculative reservations, churning and circumvention of ticketing time limits.
The airline’s ADM portal also makes clear that agencies and other GDS subscribers are responsible for ensuring their employees, agents and contractors understand the relevant booking and ticketing policies.
For agencies, this places greater importance on staff training, daily monitoring of booking queues, accurate passenger information, timely removal of inactive segments and proper authorisation of refunds and exchanges.
The financial implications can be significant because a ticketing error may involve more than the original fare difference. It can generate a debit memo, administrative charges, additional staff time and a customer-service problem that damages the agency’s relationship with its client.
As airlines increasingly use automated systems to monitor bookings and audit ticket transactions, agencies need to treat ticketing accuracy as an operational and financial control rather than simply an administrative responsibility.
For the travel trade, the real cost of an error is therefore not always visible at the moment a ticket is issued. It may emerge weeks or months later, when an airline audit turns a small discrepancy into a claim against the agency.
