Case Study: Hong Kong Express Airways achieves restored ticket inventory and increased bookings with Arkose Labs

HK Express Airways eliminates Denial of Inventory from Single Request Attacks

Hong Kong Express Airways faced severe disruption on its online ticketing platform when automated attackers reserved thousands of tickets (but never completed purchases), making fares invisible to genuine customers and causing a drop in bookings and revenue. After standard bot mitigation failed, the carrier turned to Arkose Labs and its platform—including Arkose Enforce and Arkose Detect—to address the sophisticated, automated abuse.

Arkose Labs deployed an adaptive step‑up and dynamic risk engine that accurately differentiated bots from real users, neutralized the attacks, and restored ticket inventory. As a result, attacks stopped, available fares became visible again, and bookings and revenue increased immediately; the Arkose Labs solution also reduced attackers’ ROI and adapts to evolving techniques to prevent recurrence.
