1.

It is (he successor in function of the previous International Air Traffic Association, organized in the Hague at the very dawn of regular air transport in 1919. As a non-governmental organization, it draws its legal existence from a special Act of the Canadian Parliament, given Royal Assent in December 1945.

In both its organization and its activity, IATA has been closely associated with ICAO the International Civil Aviation Organization which was &8b established in 194&as the international agency of governments which creates world standards for the technical regulation of civil aviation. IATA deals with the non-political aspects of air transport operation; its work begins only after governments have decided which companies they wish to license and how they wish to exchange traffic and other rights between them. But from that point on, the activity of IATA spreads through virtually every phase of air transport operations.
3. The basic source of authority in IATA is the Annual General Meeting, in which all active members have an equal vote. Year-
round policy direction is provided by an elected Executive Committee and its creative work is largely carried out by its Financial, Legal, Technical, Traffic and Medical Committees. Negotiations on rates and rates agreements are carried out through the IATA Traffic Conferences, with separate Conferences considering Passenger and Cargo matters.
