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).

DISH Amendment Process

New business requirements and amendments to the DISH are to be forwarded to 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.

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 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 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.
