Credible and reliable traffic forecasting is a cornerstone of airport business. It underpins infrastructure planning, investment decisions, capacity development, and revenue strategies, enabling airports to align long-term growth with evolving market demand.

The Airport Traffic Think Tank (AT3) is ACI World’s global forum dedicated to traffic statistics, forecasting, and market intelligence. It brings together airport experts to exchange knowledge, share best practices, and develop insights that support strategic decision-making across the industry.

Established in 2001, AT3 has evolved into a key platform within ACI’s economics work, supporting members through collaboration, expertise sharing, and thought leadership.

The AT3 is open to all ACI airport members and consists of experts in traffic forecasting, economics, and market analysis. As of March 2026, AT3 includes 100 airports from 56 countries, reflecting its strong global reach and engagement.
