OAG
UK company selling flight schedules and status data to airlines, GDS, and travel tech firms.
On the record
Checkpoint: Airline and GDS adoption signals for Google's Universal Commerce Protocol
The call
OAG sits as one of two entrenched aviation-data suppliers, watching whether AI-driven direct data channels start routing airlines around it.
OAG collects and sells information about flights, schedules, and airport operations to airlines, travel websites, and booking systems around the world. The company is hard to replace because it has deep relationships with over 900 airlines that have fed it data for 20+ years, and it is woven into the main booking systems that travel companies use. However, Google is building a new system called Universal Commerce Protocol that could let airlines send their data directly to AI travel assistants, cutting out OAG as the middleman. The key thing to watch over the next year is whether airlines start sending their data straight to Google and AI travel tools instead of going through OAG.
Why
01
AI pressure: Google Universal Commerce Protocol. Google's new protocol lets airlines feed schedule data straight to AI agents, cutting out data resellers like OAG. Could AI do the core job? Only partly.
02
Bigger players: Cirium (RELX). Cirium runs a live, larger-scale rival feed (300TB/day) competing head to head with OAG for the same airline and GDS contracts. Could a giant copy it? No, they are blocked.
03
What protects it. Direct 20+ year data deals with 900+ airlines and 4,000 airports, plus IATA standards ties, are hard for a new pipe to replace fast.
What would change this call
Top-20 airlines announce direct data publication into Google's Universal Commerce Protocol. Would show airlines bypassing OAG's aggregation role for AI-driven distribution.
OAG segment reporting shows redistribution revenue declining while direct-licensing also softens. Would indicate disintermediation is eroding OAG's core business model.
Cirium announces a major multi-year airline or GDS contract win previously held by OAG. Would show OAG losing ground in the duopoly to its main rival.

Key numbers
- Traces roots to 1929, about 97 years old
- Vitruvian bought OAG for $215 million
- Infare deal valued combined OAG at $500M+
Named risks
- Google UCP and agentic travel search maturing into direct airline data channels bypassing OAG's redistribution role.
- Vitruvian Partners' extended PE hold since 2017 raises possibility of sale, recapitalization, or exit pressure on strategy.
- Recurring public data-accuracy disputes with Cirium over on-time-performance rankings could erode customer trust.
- Public revenue estimates for OAG vary by nearly 8x across data vendors, indicating poor financial transparency.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Cirium | contesting | RELX-owned rival processes ~300TB/day vs OAG's 1M+ daily flight status updates, co-leader as of 2026-05-21 |
| FlightAware | contesting | Competes in live tracking and predictive analytics via AeroAPI, referenced as alternative source 2026-07-09 |
| Google (Universal Commerce Protocol) | gaining on | UCP announced Jan 2026 pushes direct airline-to-AI data channels, risking OAG's redistribution margin |
Questions people ask
- Is OAG profitable in 2026?
- OAG does not disclose financials publicly. Third-party estimates vary wildly, from ZoomInfo's ~$54.3M annual revenue (2026-07-06) to unreliable outlier estimates near $425M, so profitability cannot be verified from public data as of mid-2026.
- Who owns OAG?
- OAG has been owned by UK private equity firm Vitruvian Partners since a management buyout from AXIO Data Group valued at ~$215 million in February 2017. Vitruvian made a fresh investment alongside OAG's Infare acquisition in July 2023.
- Who is OAG's biggest competitor?
- Cirium, owned by RELX, is OAG's closest rival in a stable global aviation-data duopoly. As of May 2026, Cirium reportedly processes ~300TB of data daily from ~2,000 sources, while OAG covers over 900 airlines and ~4,000 airports.
- Could AI replace OAG?
- Unlikely to fully replace it soon. OAG's moat rests on 20+ years of direct data-supply relationships with 900+ airlines, IATA standards involvement, and GDS integrations. But Google's Universal Commerce Protocol, launched January 2026, threatens OAG's redistribution/aggregation margin via direct airline-to-AI data channels.
- Is OAG going to be sold or go public?
- No confirmed sale or IPO process has been reported as of 2026. Vitruvian Partners has held OAG since February 2017 and added fresh investment in July 2023 alongside the Infare acquisition, valuing the combined group at over $500 million.
- What does OAG do?
- OAG is a UK-based aviation data company providing flight schedules, real-time flight status, historical on-time performance, and airfare intelligence to airlines, airports, GDS platforms, and financial institutions, tracing its roots back to 1929 as the Official Aviation Guide.
