OAG

OAG is an acronym that can refer to multiple organizations and concepts, depending on context. The most common uses are in government administration and aviation data services.

Official Airline Guide is a data and analytics company in the aviation sector. It originated as a printed directory of airline schedules and flight information and evolved into a global digital platform that provides flight schedules, flight status, and route network data. OAG’s data are used by airlines, airports, travel agencies, software developers, and researchers for planning, operations, and market intelligence. The company offers real-time flight status, historical performance measures, and various aviation analytics products that support scheduling, capacity planning, and competitive analysis.

Office of the Auditor General refers to public-sector watchdogs tasked with auditing government programs and financial statements. The office typically operates independently from the executive branch and reports findings to the legislature or parliament. OAGs exist at national and subnational levels in many countries, including Canada and Australia, among others. Their work aims to enhance accountability, transparency, and the efficient use of public resources by conducting financial, performance, and compliance audits and by issuing recommendations for improvement.

Other uses of the acronym exist where organizations or programs adopt the same initials. Because OAG can denote different entities, the intended meaning is usually evident from the surrounding context or accompanying identifiers.
