ryjzjjjjjjjjjjjjjjjjjjjjjjjjThe ways of transportation are varied, and the plane holds a bigger place in United States than in other countries. United States have a dominant place in the world air transport: the biggest number of passengers, planes, the biggest airports.
             Networks are denser east of the fact of a density of more important population. The air transport is characterized by a policy of fusions and commercial alliances. The sideboard of regions is bound to the profitability only. Indeed, regions can be disadvantaged: less dense or less rich regions (lesser profitability).
             I am interested by this sector, and I didn't know it very well, so, this term paper will speak about the environment of the airlines companies, and it's decomposed into four parts: the development of the air transport, the privatisation of the airports and some examples of companies, finally the control of the airspace in United states
