BSP Data Interchange Specifications Handbook - DISH

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 provides the passenger travel industry with a set of standard formats to support the reporting of Passenger sales and ticketing data for settlement purposes.

The DISH Handbook constitutes Attachment "A" to the Passenger Services Conference Resolution 750; BSP Data Interchange Specifications.

BSP data interchange standards are jointly agreed, developed and maintained by industry experts (particularly involved in revenue accounting) participating in BSPs and the BSP Data Interchange Specifications Group (BDISG) .

What's new

The BDISG has undertaken a major analysis study of the DISH standards and has developed numerous enhancements to warrant the adoption of DISH Revision 22. This Revision represents one of the most important upgrades in recent years, and enables a lot of new reporting functions benefitting our Members as outlined below.

DISH Revision 22 (Mandatory)

DISH Revision 22 was endorsed by the Passenger Services Conference (PSC) with major amendments consisting 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
  • 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
  • New and revised DISH Appendices

DISH22 has been implemented in 2015 by all BSPs and their business partners using Chapter 4 testing procedures.

The PSC has since adopted DISH Revision 22 Update Bulletin 2016/1 with various editorial enhancements and IATA EasyPay requirements that was effective 1 June 2016.

The PSC has recently endorsed DISH Revision 22 Update Bulletin 2018/1 with enhancements relating to the reporting of Transparency in Payment requirements made effective 01 March 2018.

DISH Revision 22.2 (Optional)

The PSC has recently declared the effectiveness of DISH Revision 22.2 standards 01 June 2017.

DISH 22.2 reflects various new and revised DISH technical standards pertinent to NDC, Card-Present (EMV) and Card-not-Present (3D Secure) Authentication and other data requirements for BSP reporting.

DISH 22.2 publication is a complete replacement of DISH 22.1 and DISH 22.1 Update Bulleting 2016/1 Revisions which have been made obsolete.

DISH 22 & 22.2 Implementation Downloads

The following documents are to be used to support the DISH 22 and DISH 22.2 Implementation Process:

DISH Amendment Process

  • New business requirements and amendments to the DISH are to be forwarded to dish@iata.org using the DISH Amendment Form (doc). The proposal 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.
  • When a new business requirement or an amendment necessitates urgent implementation, e.g.: a change in government regulation, an electronic procedure known as the PSC mail vote is used to expedite the change. This only applies to exceptional urgent items.
  • All agreed amendments become effective on the date recommended and published in the next Revision of the DISH.
  • Implementation plans are coordinated by IATA and are driven by the testing procedures outlined in DISH section 4.3.5.

Key Benefits of DISH

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. 

The Handbook specifies the formats, specifications and data fields used in BSPs for the following DISH files and business functions.

  • Agent Reporting (RET);  agents reporting via the Global Distribution Systems (GDSs) to the BSP
  • Airline Accounting/Sales (HOT);  hand off transmission and accounting data file from the BSP
  • Credit Sales Invoicing (CSI);  transactions produced by the BSP for the credit card company or airline
  • Ticket Inventory Data (TI);  allocation of STD numbers to BSPs, ticketing systems and airlines
  • Credit Card Settlement Plan (CSP);  invoice data from BSPs to the credit card company, bank, airline or UATP contractor airline

DISH describes the status of availability and identifies the functional use of data elements. It also serves as a development tool for BSP systems and their interfaces with BSP participants.

The DISH contains set testing procedures used for implementation processes and conforms to provisions of the IATA Passenger Services and Agency Conference Resolutions, Ticketing handbook and Airline Coding Directory.
