How Booking.com Uses Snowflake Cortex AI to Unify 31M Travel Listings

Booking.com operates at a scale that makes data infrastructure a strategic necessity rather than an operational detail. The platform connects hundreds of millions of users to 31 million travel listings — hotels, flights, rental cars, attractions — across 175,000 destinations in 220 countries and territories. At that volume, generating hundreds of petabytes of data, the ability to move quickly and reliably on insights determines whether the platform stays competitive.

For years, Booking.com ran its Big Data and AI workloads on an on-premises Hadoop ecosystem. During peak travel seasons, the cracks were impossible to ignore: workloads faced significant delays, data quality was inconsistent across teams, and users struggled to locate the right data with confidence. Assembling the data needed to deliver a “connected trip” — the company’s vision for seamlessly linking every stage of a journey — was an increasingly complex problem that the on-prem stack couldn’t support.

Booking.com migrated to Snowflake’s cloud data platform, consolidating its Big Data and AI workloads into a scalable, high-concurrency environment. The team deployed Snowflake Cortex AI to make data exploration accessible across the organization through a centralized catalog, where anyone can discover and query data without deep technical overhead. Native governance controls address both GDPR and the EU AI Act — giving the team precise visibility into what data exists, how it is classified, and who holds access at any given time.

The impact was immediate and organization-wide. The “wild west” dynamic of the Hadoop era gave way to a reliable, fast platform. Connected trip transactions increased, and the velocity of the underlying infrastructure allowed Booking.com to stay ahead of competitors in delivering a premium travel experience. Snowflake Cortex AI reduced the friction of data discovery significantly, enabling faster decisions across customer support, product development, and operations.

Booking.com now treats Snowflake as the foundation for its next phase of travel innovation. With self-service data access democratized and compliance built into the platform, the team is focused on deepening the connected trip — ensuring every touchpoint from flight research to hotel check-in is informed by real-time, trusted data across 220 countries.
