BSP Data Interchange Specifications Group (BDISG)

BSP Data Interchange Specifications Group (BDISG) site is where BDISG meeting details and Data Interchange Specifications handbook (DISH) related information is updated and made available.


The Private portion of the Web site is reserved for Member Airlines and qualified Strategic Partnership Members registered within the Passenger and Airport Services area and involved in IATA Passenger Settlement Systems in providing agent reporting data (RET) to a Billing and Settlement Plan (BSP). Companies and organisations interested in BSP Data Interchange Standards are invited to join our IATA Strategic Partnerships.

The BSP Data Interchange Specifications Group (BDISG) is established by the Passenger Services Conference (PSC) to develop and maintain technical solutions within the BSP Data Interchange Specifications Handbook (DISH) for the exchange of passenger ticketing and related data between travel agents and airlines for remittance and settlement purposes.

Meetings of the BDISG are open to all IATA member airlines (particularly involved in revenue accounting) and to BSP partners within the IATA Strategic Partnership Programme providing RETs to BSPs.

BDISG participants have the opportunity to model the standards based on business requirements. The BDISG alsoliaises with other industry committees directed under the Passenger Services and Passenger Agency Conferences to progress DISH developments.

The BDISG Terms of Reference are accessible via the link located on the right hand side of this webpage.

BDISG Activities

One of the main objectives of the BDISG is the minimization of local requirements, cost reduction, and decreasing inconsistencies. The BDISG has undertaken a major analysis study of the DISH standards and has developed numerous enhancements to warrant the adoption of a new DISH Revision 22 (pdf).

This Revision represents one of the most important upgrades in recent years, and will enable a lot of new reporting functions benefitting our Members as outlined below.

The Passenger Services Conference (PSC) endorsed Revision 22 of the DISH and has declared it effective as of 1 January 2014. Major amendments consist of:

  • New data elements to support EMD requirements for airlines and credit card acquirers
  • The reporting of coupon-level taxes made possible for airlines
  • New data elements and records for the netting reporting of exchanges for airlines
  • A complete revision of the DISH publication to reflect:
    • Alignment procedures and formats to the PSC Resolutions
    • Elimination of obsolete data elements and references to all paper documents
    • Restructuring of Records for improved flexibility

DISH 22 is to be implemented by all BSPs and their business partners as per a set schedule, outlined in the DISH Factsheet (pdf), and that will be coordinated by the IATA DPC Management team with all stakeholders. Testing procedures in Chapter 4 are to be followed.

The Passenger Services Conference (PSC) declared the effectiveness of DISH Revision 22.1 standards as of 01 June 2015. 

DISH 22.1 reflects requirements to support the Card-Present (EMV) and Card-not-Present (3D Secure) Authentication data for BSP reporting and is presented as an optional release for those BSPs implementing Card Authentication standards.  Enhancements are outlined within the Summary of Changes listing and are published as replacement pages within a complete updated DISH 22.1 document.

DISH is the global data interchange standard implemented by all Billing Settlement Plans (BSPs), to ensure consistency and the exchange of the highest possible quality data between BSPs and GDSs, airlines and other business partners.

The DISH defines the reporting standards to enable GDSs to report ticket and miscellaneous documents sales made by BSP travel agents to the IATA Data Processing Centers, to enable the Sales data to be provided to airlines and credit card acquirers, and aids Remittance and Settlement. Further information on DISH and file downloads of publications are accessible via the BSP DISH.

New business requirements and amendments to the DISH are to be submitted to the attention of the BDISG Secretariat using the DISH Amendment Form (doc). Proposals will be submitted to the next meeting of the BDISG.

Proposed amendments to DISH discussed and agreed at BDISG are endorsed by the PSC for adoption as an IATA standard. Implementation plans are coordinated by IATA and are driven by the testing procedures outlined in DISH section 4.3.5. Questions?  Email dish@iata.org
