The aviation industry's digital systems are often invisible to the traveller until something fails: a reservation does not update, a departure gate changes, a baggage connection breaks, or an identity check creates a queue. Technology and data affect how airlines sell, plan and recover flights, and how airports manage capacity and passengers. Somit Goyal examines the challenge of replacing airline legacy systems and distinguishes modern distribution standards from a complete retail strategy. Sunil Ankalgi considers the operational technology running inside airports, while Suresh Khadakbhavi discusses Digi Yatra's identity architecture and consent questions. Mike Malik and Courtney Miller approach the field from performance metrics, forecasting and decision support. This hub focuses on the connection between data, software, governance and measurable operational outcomes; airport construction and fleet manufacturing are separate subjects. It also treats vendors' predictions as claims to examine, not results to assume.
