Thus, for example, the Settlement System participants were offered a new settlement and reporting technology that significantly simplified reporting procedures for accredited agencies and reduced timeframes of revenue settlement for ATSS participating airlines. TCH System of Interactive Reporting was upgraded so as to enter Reason for Memo Issuance Code (RMIC). The carrier can use RMIC for systematization and analysis of processed ACM data in own accounting system. In accordance with international requirements to traffic document issuance the Settlement System implemented an upgrade enabling to show ticket number in CCS-TCH Electronic Miscellaneous Document (EMD). TCH launched new edition of Information System "Statistika" into commercial operation developed to enhance quality of statistical reporting and reduce timeframes of delivery of such reporting and unbiased and detailed analytical data to state administrative authorities, air transport enterprises and organizations. TCH experts were developing a universal system for payments using bank cards and other e-payment tools -TCH Payment. Moreover, in 2015, TCH started updating the System of Interactive Interchange which was renamed into TCH Connect in the vein of TCH rebranding, and was targeted to enable airlines, agencies, providers and TCH partners to interact with TCH systems and access TCH databases.

TCH representatives were chosen as members of the Form Codes Working Sub-Group. As a result of negotiations on Forms Codes between IATA, ARC and TCH, it was resolved to reassign Form Codes 611, 613, 617 and 619, which were allocated to TCH back in 1994. Besides, it was proposed to retain these three-digit codes for CCS-TCH traffic documents as "TCH property", and in June 2017, assign codes 611, 613 and 617 to ET – for ATSS-TCH agencies and Code 619 – to EMD for ATSS-TCH agencies.
