We have integrated into our processing chain an advanced quality control engine: Compleat.
This intelligent mid-office automatically checks each booking before issuance: analytical consistency, compliance with travel policy, control of high-risk segments (e.g. international departures, long-haul flights, open-jaws), and budget alerts. It can also rebook to a more advantageous fare class, intercept a code-share, or block the issuance of a PNR if a major discrepancy is detected.
