OAG Tech Stack

Global travel data platform covering schedules, pricing, and demand signals

Airlines and Aviation Luton, Bedfordshire 201–500 employees Founded 1929 Privately Held

OAG operates a data platform serving airlines, airports, and travel companies with flight schedules, pricing, and demand intelligence. The tech stack spans Angular/React/Vue frontends, .NET/.NET Core backends, and a multi-cloud data layer (Postgres, SQL Server, Snowflake, GCP, AWS, Azure), with active migration toward Databricks while phasing out Snowflake — indicating a strategic shift toward unified analytics. Heavy engineering hiring (10 open roles) paired with data (4) and sales (2) roles, alongside concurrent projects in web-crawler scaling, warehouse transformation, and cloud-native backend work, signals rapid operational expansion under constraint of legacy system decommissioning.
