Agent Debit Memo (ADM) is the legitimate accounting tool used by airlines to collect adjustments for Standard Traffic Documents (STDs) issued by Agents (Reso 850m) (pdf). In 2015, airlines have issued 2.3 million ADMs transactions for a value of US $ 579 million, incurring an estimated industry cost of US $ 150 million to manage the ADM process.

The cost incurred by the industry for the management of ADMs is extremely high. To respond to this issue, the Passenger Agency Steering Group had established a dedicated ADM Strategy Group as well as the ADM User Group (Formerly referred to as ADM Working Group) in order to support industry initiatives that would facilitate ADM reduction and improved ADM management.

What do Airlines and Travel Agents have to say about ADMs?

The ADM Reduction Project team conducted an ADM Market Analysis to get market-based data around the topic of ADMs from IATA Member Airlines and Accredited Agents. The ADM Market Analysis Report provides intelligence that will help IATA building a strategy to promote the ADMWG/ADMUG best practices in a more efficient manner.


The ADM Management & Reduction Project has initially been endorsed by the Passenger Steering Group (PSG). It has been initiated in order to support the formation of the ADMUG and facilitate the initial phases of establishing standards and initiatives. The objectives of this project are to:

  • Reduce the need for ADMs in various areas, thereby reducing the workload, resources and time spent on post-billing revenue auditing
  • Streamline various work processes and enhancing the ADM process, creating a lean post-billing settlement process
  • Enhance the communication process within the existing workflow and improve business relationships

After identifying inefficiencies in the current distribution chain, solutions found within the ADMUG are resulting in a reduced need for post-billing revenue recovery via ADMs, and their implementation started taking place in 2017 and is on-going.

More information on the need to reduce ADMs (pdf).

Three workshops facilitated by the IATA ADM Management & Reduction project team brought the ADM User Group members to go through ADM data and define the main reasons for ADMs. Several solutions were identified and agreed on through a final roadmap that will result in a reduced number of ADMs.

The Standard reason codes document describes the main reasons for ADMs

In 2018, the ADM User Group worked on the implementation of these solutions (pdf), which have been categorized in three different streams:

Technical Solutions

A set of different system enhancements to provide easy access and transparency to information and a self-service platform including a Policy Repository, BSP commission control and Credit Card Acceptance. The Root Cause Analysis showed that the lack of such information was a major reason for ADMs.

Best Practices

A set of rules and practices (pdf) that will help all industry actors impacted by ADMs to better manage those by providing the necessary access to relevant information.


A set of different trainings targeted to specific audience (Airline or Agent) for a better understanding of ADMs, aiming for a better management of the related processes.

Join the ADM User Group (ADMUG)!

The aim of ADMUG is to improve the efficiencies in the current distribution chain and works on identifying, developing and implementing solutions resulting in a reduced need for post-billing revenue recovery through ADMs. ADMs are a well-known challenge for the industry, therefore all industry actors (Airlines, Agents and their Associations, GDSs, ATPCO, ARC & IATA SMEs) are called to work together in a data-focused environment to reach that goal.

This is why any Airline, Agent, Travel Agent Association or GDS entity interested in contributing to the group by providing input with a collaborative, data-driven mindset is invited to join the ADMUG. For receiving more information, participating in the user group's discussions and be part of the solution, please feel free to join the ADMWG extranet, or contact us through

The ADMUG Recognition Program

The ADM User Group (formerly referred to as ADMWG) has worked diligently since 2015 to bring industry experts together in the global fight against Agency Debit Memos (ADMs). This Recognition Program aims to recognize and award the hard work of the ADMWG members who have provided with significant contributions to the development of solutions and best practices that have simplified the processes and challenges related ADM’s.

Educational video on ADM prevention in collaboration with ATPCO

The ADM Reduction Project team brought together two experts from IATA and ATPCO to talk about ADMs related to the management of exchange and refund rules. Learn about their specific tips on the three “categories” in which the airlines can instruct their policies for voluntary changes and refunds.

Training for Airlines and Agents

In a coordinated effort with IATA Training team, specific training needs have been identified to address common ticketing errors that lead to ADMs.

Training for Airlines

  • Customized training for your Airline based on your historical ADM data, to better understand pain-points causing ADMs issuing for automated fares
  • A better understanding of fare construction that will empower your staff in filing fares and accurately reflect your Airline’s intent

If you are interested in receiving a customized training portfolio based on your Airline’s ADM data, please contact us at

Training for Agents

  • Handpicked ticketing courses that will help your consultants enhance their knowledge on specific areas proven to be the main reason for human error and resulting in ADMs
  • If you are interested in ticketing courses that will help you prevent ADMs, please go through the below online modules and find the list of available courses at the end of each level

Credit Card Chargebacks and Fraud Prevention

Credit card chargebacks have consistently represented about 11%* of the total value of ADMs globally over the last three years. This is equivalent to over USD140 million of revenue leakage in 3 years time!

While the main reasons for such high chargeback ADM values have yet to be fully identified, discussions among the ADM User Group highlighted two of the biggest challenges facing the industry in trying to reduce them:

  • Tight timelines allowed to airlines for providing evidence to adequately challenge and remedy chargebacks
  • Raising the level of awareness about the importance of fraud prevention at the point of sales

To overcome ADMs and chargebacks, the ADMUG in collaboration with IATA’s Industry Fraud Prevention initiative, presents Credit Card Chargeback Guideline (pdf) , a guide that provides a compilation of best practices and useful information in order to help the industry prevent the occurrence of card chargebacks related to ADMs.

Read the full interview of two payment experts from ARC and IATA discussing how ADM reduction could be an indication of fraud prevention.
