OAG Improved Reporting with Tableau
to Microsoft Power BI Mig
Client Overview
Official Aviation Guide (OAG) is a UK-based industry-leading travel data platform that’s been powering aviation intelligence since 1929. With nearly a century of experience, they deliver supply, demand, and pricing datasets via cloud-based APIs and analytics tools. OAG supports the global travel ecosystem by providing insights into flight schedules, status, connections, and historical performance, enabling more informed decision-making across airlines, airports, consultancies, finance, travel technology, and government agencies. Their offerings include nearly real-time data, analytics like the OAG Analyser suite, alerts, and comprehensive historical archives. Operating globally, from the UK headquarters to offices in the USA, Asia, and Lithuania, OAG powers billions of travel decisions each day through its rich, trusted data infrastructure.
Business Objective
The primary objective of the OAG is to migrate all existing reports and dashboards from Tableau to Microsoft Power BI. While migrating, they wanted to keep Snowflake as the central data source. The intent to migrate away from Tableau was to achieve seamless integration with other Microsoft products like Teams, Azure, and Excel, improve dashboard rendering speed, and reduce licensing costs.
