MATIP Flow ID

The Mapping of Airline Traffic over Internet Protocol (MATIP) flow identifier (ID) user exit, UMATFI, allows Societe Internationale de Telecommunications Aeronautiques (SITA) host-to-host communication to allocate message charges to the appropriate host airlines. The byte contents are agreed on an airline-to-airline basis for billing purposes.

UMATFI is called in CMADAT.
