Aegean Air Sees International Sales and Online Fraud Skyrocket

Aegean Airlines is the largest carrier in Greece. With 87 international destinations in 32 countries and 33 domestic airports to service, this Star Alliance member continues to attract an increasing number of international passengers. Unfortunately, with increased international traffic has also come an increased incidence of fraudulent transactions.

Highly Customized ReD Shield® Solution Grounds Fraud

To combat this trend, ACI worked closely with Aegean to implement a highly customized version of the ACI ReD Shield® online fraud prevention solution. This move gave Aegean the ability to view key transaction trends quickly and easily and obtain other valuable information that helps to implement timely and effective rule changes where needed. Core to the new strategy was a focus on critical issues, such as consistently prioritizing short notice bookings in the fraud screening process.

Established Rules Stop 97% of Fraud

The first year of collaboration between ACI and Aegean Airlines yielded measurable results. Benefits include:

•      97% of all confirmed fraud was denied by established rules, saving the airline 3 million euros
•      Manual review rates dropped from 12% to less than 5%
•      Chargeback rates plummeted to less than 0.1% on average

Cost savings and efficiencies achieved have enabled Aegean Airlines to extend the solution to cover call center transactions without any additional resource requirements to support fraud screening.
