​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.

One of the main objectives of the BDISG is the minimization of local requirements, cost reduction, and decreasing inconsistencies.

About 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 defines the reporting standards to enable GDSs (Global Distribution Systems) to report 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 (standards@iata.org) using the DISH Amendment Form (doc) and Agenda Template for non technical matters (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 and scenarios outlined in DISH section 4.3.
