Case Study: Aegean Airlines achieves 97% fraud denial, €3M in savings and secure international sales with ACI Worldwide

Reducing Risk and Supporting International Sales at Aegean Airlines

Aegean Airlines, Greece’s largest carrier, was seeing rising multi‑channel fraud as international bookings grew—especially short‑notice bookings (81% of fraud) and transactions on U.S. cards that threatened its U.S. sales channel. After a thorough selection process the airline engaged ACI Worldwide, selecting ACI ReD Shield as part of the ACI Omni‑Commerce solution to reduce risk and protect genuine international sales.

ACI Worldwide’s risk analysts conducted a six‑month data review, tuned rules and implemented a customized ACI ReD Shield/ACI Omni‑Commerce deployment with case management and bespoke reporting, staying onsite for go‑live support and prioritizing short‑notice bookings. The results: rules denied 97% of confirmed fraud (saving €3 million), manual reviews fell from 12% to under 5%, chargebacks dropped to below 0.1%, and the solution was extended to call‑center transactions without additional resources.
