Case Study: Largest Airline Service Provider achieves scalable, modernized legacy flight operations with Hexaware

Re-engineering Consultancy for Legacy based Flight Operations System

Largest Airline Service Provider — the world’s oldest and largest airline service provider with a combined fleet of 500 aircraft and more than 1,500 daily departures to 900 cities in 160 countries — faced a brittle Unisys OS2200–based flight operations suite (routing, scheduling, ACARS, FLIFO, MEL/MGL, weight & balance, gate handling) that suffered from poor scalability, a primitive UI, rigid inter-application protocols, high technology overhead and scarce legacy skills. Hexaware was engaged to re‑engineer this legacy flight operations system.

Hexaware conducted a Discovery Phase to define the re‑engineering roadmap, perform code mining, market-watch for off‑the‑shelf components and deliver build‑vs‑buy analysis and indicative budgets. Hexaware recommended a phased Java/J2EE implementation on an SOA layer with a mix of re‑engineering and selective replacement using scalable off‑the‑shelf components; this approach reduced coupling, enabled future connectivity, improved scalability, modernized the UI and accelerated time‑to‑market. While the case study does not publish quantitative metrics, Hexaware delivered a concrete implementation plan, cost estimates and component choices that positioned the customer for measurable gains in performance, maintainability and operational efficiency.
