Airports Council International
From AltData.wiki, The Alternative Data Encyclopedia
Airports Council International (ACI) is the global trade association of airport authorities, representing the world's airports before governments and international aviation bodies such as ICAO and IATA. Established in 1991, its world governing body (ACI World) is based in Montreal, Canada, and operates as part of a federation alongside five regional associations covering Africa, Asia-Pacific and the Middle East, Europe, Latin America and the Caribbean, and North America.[1][2][3].
Although primarily an advocacy and standards body, ACI is a significant data provider for the aviation sector. It publishes airport-level traffic statistics — passengers, cargo, and aircraft movements — including the Annual World Airport Traffic Dataset, quarterly Airport Industry Reports, and global busiest-airport rankings, which analysts use as official benchmarks for air travel demand.[1]
What It Does
ACI represents the collective interests of airports in policy development, working with international organizations and regulators to develop policies, programs, and best practices for airport safety, security, environment, economics, and passenger facilitation. It also provides education and training, accreditation programs, peer assessments, and industry data and reports.[1]
As a membership organization, it serves airport owners and operators as regular members, plus businesses working with airports through its World Business Partner program. As of January 2025, ACI reported serving 811 members operating over 2,200 airports in more than 160 countries.[1][2]
Data and Methodology
ACI's statistical work is anchored in member-reported operational data, aggregated monthly and annually into datasets covering passenger traffic, cargo volumes, and aircraft movements by airport. Its flagship commercial dataset is the Annual World Airport Traffic Dataset, sold through its online store, complemented by the quarterly Airport Industry Report and a traffic forecasting whitepaper series.[1]
The Airport Service Quality (ASQ) program supplies a second data stream: passenger satisfaction surveys conducted with travelers on their day of travel at participating airports, feeding benchmarking services and the ASQ Awards.[1][2]
Products
Data products include the Annual World Airport Traffic Dataset, the Airport Industry Report (published quarterly, e.g., Q1 2026), the ACI World Airport Traffic Forecasting Whitepaper, and rankings of the world's busiest airports by passengers and cargo. These are distributed through the ACI Store, the ACI Data Center, and the online Intelligence Hub.[1]
Non-data offerings include ASQ customer experience solutions, accreditations such as Airport Carbon Accreditation, the APEX peer review programs in safety and security, and diploma-style training programs for airport professionals.[1][2]
Buyers and Use Cases
Primary buyers of ACI data are airports themselves, aviation consultancies, aircraft manufacturers, investors, and media tracking air travel trends. Because the figures come from operators through an authoritative industry association, ACI traffic numbers are widely cited as reference statistics for airport throughput.[1][2]
In an alternative data workflow, ACI's published datasets serve as ground-truth calibration for higher-frequency proxies of travel demand, such as flight-tracking feeds or mobility data, rather than as a real-time signal itself; the association publishes periodic releases rather than streaming data.[1]
History
Before 1970, airports were represented by three separate associations — the Airport Operators Council International, the International Civil Airports Association, and the Western European Airports Association — which coordinated through the Airport Associations Coordinating Council from 1970. The decision to create ACI was taken in 1989, its constitution was approved in autumn 1990, and the organization came into effect in 1991.[2]
ACI relocated its headquarters from Geneva to Montreal in 2011, in part because ICAO and IATA are also located there. Regional offices operate in Washington D.C. (ACI North America), Brussels (ACI Europe), Panama City (ACI LAC), Hong Kong (ACI Asia-Pacific), and Casablanca (ACI Africa).[2]
Landscape
Within the Supply Chain and transport data landscape, ACI occupies the role of an official industry source comparable to what IATA provides for airlines. Its datasets compete less with commercial alt-data vendors than they complement them, offering audited baselines against which faster but noisier signals can be validated.[1]
