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 a new DISH Revision 22. 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.

DISH Revision 22 major amendments

  • 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
    • The elimination of obsolete data elements and references to all paper documents
    • Restructuring of Records for improved flexibility

Implementation of DISH Revision 22

DISH22 is to be implemented by all BSPs and their business partners as per set. Implementation Timelines as agreed by the BDISG.

High level implementation timelines are as follows:

  • January through June 2015 – Testing, certification and sign-offs for Pilot BSP Countries
  • August through December 2015 – Rollout for non-Pilot BSP Countries

Please refer to the DISH 22.0 Implementation Plan sections 11.2, 11.3 for more information on the implementation timeframes for particular BSPs. Testing procedures in Chapter 4 are to be followed.

DISH Revision 22.1 (optional)

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 DISH22.1 document (File under Related Links).

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 shall be 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
  • Market Share Analysis Data (MSA);  reported by the BSP on request from the 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.
