DMWG History and Mission

The DMWG's Mission

The DMWG's mission is to improve the efficiency of the debit memo process, and ultimately reduce the volume of invalid memos, by working together for common solutions that benefit the industry as a whole.

How has the DMWG impacted the air travel industry?

The DMWG's work is ongoing, with meetings held every two months by phone, and twice annually in person. There have been a number of significant accomplishments since the DMWG was established in 2013. Here are a few highlights:

  • The launch of Memo Analyzer, an online tool that provides insight into memos and ticketing data for agents, carriers and system providers. As of August 2017, Memo Analyzer has mapped standard debit memo reason codes for 23 major carriers, with more carriers to be added in the near future.
  • The creation of standard debit memo reason codes. After manually reviewing over 44,000 memos to identify patterns and root causes in debit memos, the DMWG established standard debit memo reason codes that are now used throughout the industry. These standardized codes have now been implemented in Memo Analyzer, and the ultimate goal is to incorporate these codes in Memo Manager, as well.
  • VISA initiates industrywide change by amending rules to help reduce credit card fraud by accepting airline-supplied flight manifests as a remedy for fraud-related credit card chargebacks. Since this change, Mastercard has begun accepting flight manifests as compelling evidence for fraud-related chargebacks.
