Modernized passenger service

Use case: Modernized passenger service


A major domestic and international airline serving hundreds of airports across six continents around the world needed to modernize operations with a new Passenger Service System (PSS) to grow its brand to be recognized as an international airline of choice.


  • The outdated PSS cost a lot of time and money to add basic features and functions, making it complex and difficult to use
  • Employees were using 30+ applications to process passenger information
  • Unable to effectively work with other airlines and travel partners


  • Integrated new PSS with 80+ subsystems and 20+ consuming applications
  • Built 80+ APIs to connect and process passenger data across 160+ interfaces
  • Modernized Departure Control System (DCS) within PSS with APIs


  • Annual future cost savings of $100 million
  • Enabled expansion into new markets, partnerships, and revenue opportunities
  • Enhanced system-to-system integration and communication
