ADM Policy - Five Forty Aviation Ltd dba Fly540

In accordance of the IATA Resolution 850m (Passenger Agency Conference Resolution Manual) Five Forty Aviation Ltd. takes the opportunity to specify the Five Forty Aviation Ltd. Revenue Recovery policy concerning the Reservation- and Fare Audit process and the related procedures of sending and settling ADM’s (Agency Debit Memo). All resolutions agreed by the Passengers Agency Conference will be applied.


ADM Principle

The objective of the audit process is to ensure that all fare rules and procedures are respected and in case of the contrary, to settle the difference in an adequate and logical way, equal for all distribution channels. Fare audit checks are performed on all ‘540’- document issuances, refunds, reissue and revalidation transactions, whether they are fare quoted automatically or manually. Violations of reservation procedures apply to all 5H flight segments.


ADM Calculation & Minimum ADM Value

In case deviations of the fare rules are found during the audit process, Five Forty Aviation Ltd. will systematically generate ADMs reflecting the value of difference between the real applicable fare and the applied fare plus the ADM fee. (Except for those cases where fixed amounts apply)

The minimum ADM value is USD 10 or equivalent. In case of persistent practice of under collection (multiple occurrences of underpayments of less than USD 10 or equivalent) by the same agent, Five Forty Aviation Ltd. reserves the right to recover these underpayments. More than one ADM in relation to the same original ticket can be raised if different, unrelated charges apply.

Grouping of multiple tickets on one ADM can be allowed under conditions that the audit reasons are the same for all grouped tickets and all tickets are issued by the same agent. Grouping by refund errors is technically not possible.


ADM Administrative Fee

To cover the audit process costs, a fixed ADM administrative fee of USD 10 or equivalent is added to each ADM. The administrative fee will not apply to ADMs under the minimum ADM value.

In the event that disputed ADMs result in withdrawal from BSPLink (for other than commercial reasons) by Five Forty Aviation Ltd., the administrative fee will be refunded to the travel agent if already collected.


ADM Settlement

Agency Debit Memos will be settled via the BSPLink if sent within nine months after final travel date. Beyond that date payment settlement will be handled directly between the airline and the agency. ADMs are issued via mass-upload once a month.

ARC Debit Memos will be loaded in the ARC Memo Manager.

Non-BSP countries will receive ADM proposals by invoice once a month.


ADM Dispute Handling

Agents can dispute proposed ADMs directly via BSP Link with no financial consequences if supported by a valid dispute reason and/or supporting documents. Five Forty Aviation Ltd. will endeavor to handle a rejected or disputed ADM in a timely manner, within maximum 60 days. In case Five Forty Aviation Ltd. rejects an agent dispute, an explanation for this rejection will be provided to support our position.


ACM Issuance

In case of unjustified ADMs been issued by the airline or when an ADM requires corrections in favor of the agent, an ACM can be issued to that agent covering the amount due.


ADM Reasons

In particular subject to audit are:
