Case Study: Major International Airline achieves $6.2M annual revenue gain and 300% ROI with Splunk

How Splunk Software Helped a Newly Merged Airline Take Off

A newly merged international airline with more than $5 billion in annual revenue was losing customers and revenue because its high‑traffic website was slow, transactions stalled or dropped, and support calls were rising. Multiple front‑ends, siloed systems and disconnected logs left analysts blind to why passengers abandoned bookings and prevented the airline from understanding per‑flight profitability.

The airline deployed Splunk to ingest and correlate Sabre, Apache, log4j and homegrown logs, creating real‑time dashboards and alerts that traced transactions end‑to‑end and revealed root causes. The result: a 60% lift in conversions (+$1.3M/yr), improved site experience and retention (+$2.9M/yr), 80% fewer escalations (saving $800K/yr), 50% lower problem‑resolution costs (>$1.2M/yr), an investment recouped within months and roughly 300% ROI in year one (≈$5M value; projected $15M by year three).
