BSP Data Interchange Specifications Group (BDISG)
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.
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
New business requirements and amendments to the DISH are to be submitted to the attention of the BDISG Secretariat (firstname.lastname@example.org
) 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 and scenarios outlined in DISH section 4.3.
The PSC has endorsed new business requirements and numerous enhancements to DISH standards included within a new Revision 23 publication, declared effective 1 April 2018.
DISH Revision 23 has been developed to reflect a worldwide data interchange standard to be implemented by all Billing and Settlement Plans (BSPs) ensuring the highest possible quality data is exchanged between BSPs, airlines and strategic partners.
In order to produce Revision 23, major amendments include:
- Addition of 3DS and EMV data elements and records for card transactions
- Transparency in Payments (TIP) requirements for alternative payment methods aligned with PSC Resolution 728 on form of payment codes
- New data elements and RET/HOT records to support Complex Taxes Fees and Charges–Additional Coupon Tax Data
- New data elements and RET/HOT records to support GST related information
- CSI file format defined as a Mandatory layout for card transactions
- Complete revision of Testing/Certification Procedures and RET/HOT Data Quality Assurance in DISH Chapter 4
- Exempted taxes reflected within the TMFA & TMFT data elements
- New Diners/Discover and JCB specifications to the FPTI data element
- Addition of other new data element indicators related to Change of Gauge, Commission Control Adjustment, Arrival Date, Arrival Time, Departure Terminal and Arrival Terminal
- Mandatory/Conditional Status modifications to records and fields in alignment to PSC & Ticketing Resolutions
- Modification of CSI and CSP data elements status anomalies
DISH 23 replaces all previous Revisions and is presented as a mandatory Revision. Testing procedures and scenarios in Chapter 4 are to be followed.
Composition and Meetings
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 Program providing RETs (agent reporting data) to BSPs.
BDISG participants have the opportunity to model the standards based on business requirements. The BDISG also liaises with other industry committees directed under the Passenger Services and Passenger Agency Conferences to progress DISH developments.
There is no restriction on the number of participants and they meet once a year.
