Cirium vs OAG

OAG's own comparison is to Cirium directly — both license aviation schedule and status data, but Cirium's remit extends further into fleet and tracking.

Verdict

OAG's tool record names Cirium as its closest competitor, and the overlap is real: both are enterprise aviation-data providers delivering flight schedules, status and historical data via API to airlines, airports and travel-technology companies, both are quote-priced through direct sales, and both are owned by larger information conglomerates (Cirium by RELX via LexisNexis Risk Solutions; OAG independently but with similar enterprise-data positioning). The difference is breadth. OAG's core strength is schedule data specifically — more than 900 airlines, updated roughly every 15 minutes, with over 20 years of historical schedules, delivered with a notable Snowflake data-share integration. Cirium covers schedules too, but extends further into live flight tracking, a global aircraft fleet database, passenger traffic data and aircraft emissions data, making it the broader aviation-data platform of the two.

Choose OAG if

  • Schedule data specifically — current, historical or airfare-adjacent — is the primary need, and you want deep historical depth (20+ years) and frequent update cycles.
  • You already use Snowflake and want data delivered as a data share rather than only via API.
  • Seating-capacity data alongside schedules matters for your route or network analysis.

Choose Cirium if

  • You need flight tracking and fleet data in addition to schedules, not schedules alone.
  • Emissions and aircraft-utilization data are part of the requirement — increasingly relevant for airline sustainability reporting.
  • Being part of a larger risk-and-data infrastructure group (LexisNexis Risk Solutions) is a plus for procurement or data-governance reasons.

What they share

Neither publishes pricing; both license data and analytics through direct sales contact rather than self-service tiers, consistent with enterprise aviation-data agreements generally. Both deliver via API and dashboard rather than requiring a full consulting engagement to get started. If your need extends beyond schedules and tracking into aggregate booking-demand intelligence, see Amadeus Travel Intelligence, which draws on a different data source (global distribution system bookings) than either of these.
