Airports Council International (ACI) is the association of the World's airports. Based in Montreal, it is a non-profit organisation, whose prime purpose is to advance the interests of airports and to promote professional excellence in airport management and operations.

By fostering cooperation amongst airports, world aviation organisations and business partners, ACI makes a significant contribution to providing the traveling public with an air transport system that is safe, secure, efficient and environmentally responsible.

As the international association of the worlds' commercial service airports, ACI represents the collective positions of its membership, which are established through committees and endorsed by the ACI Governing Board. These views reflect the common interests of the global airports community.
