ICH, Non-ICH Runs, and ACH

Carriers in the air transport industry are members of Clearing Houses that assist them in interline billing and settlement. The interline prorate runs are categorized according to clearing house membership.

There are three clearing house memberships available:
  • Members of the IATA Clearing House (ICH)
  • Non-members of the IATA Clearing House (Non-ICH)
  • Members of the Clearing House in the United States (ACH)
The interline prorate runs can be found in the Interline (PRORATE_) node of the Report Menu screen.
