How an API-Led Integration Helped Modernize Airline Operations Saving $100M+ a Year

About the Client

A leading international airline, operating across six continents and serving over 50 million passengers annually, faced a growing challenge: its decades-old Passenger Service System (PSS) was outdated, complex, and slowing down growth.

With a vision to scale efficiently and improve customer experience, the airline turned to a modern integration strategy to overhaul its core systems—without disrupting daily operations.

The Challenge

Built in the 1970s, the airline’s legacy PSS lacked customization, flexible interfaces, mobile capabilities, and system-to-system integration. It couldn’t keep pace with modern airline operations or support connections with key partners and travel systems.

The Solution

Bits In Glass helped modernize the airline’s operations with an API-led integration approach, enabling smarter, faster, and more scalable service delivery.

Highlights included:

  • Integration of the new Altea PSS with 80+ subsystems and 200+ applications
  • Automation of Departure Control System (DCS) tasks like baggage handling and flight data
  • Improved collaboration with partners and travel agencies

The Results

  • $100M+ in annual savings
  • 2,000+ transactions per second—supporting high-volume traffic with ease
  • Fastest and smoothest technical go-live in the airline’s history
  • Accelerated time to market for new offerings and services
By replacing legacy systems with intelligent automation and seamless integrations, the airline unlocked operational agility, reduced costs, and created a foundation for future growth—taking its passenger experience to new heights.
