ABSTRACT
In the United States air carriers, in order not to conflict with the antitrust laws, cannot meet to discuss scheduling, routes, services or, of course, fares (although they can and do meet frequently to discuss security and gate arrangements). Partly because of this there are few restrictions at US airports limiting the allocation of landing and take-off slots; for example airline scheduling committees which have an important slot management role outside the United States do not operate at US airports.
