Abstract:
Since its inception, the air transport market has been a strategicall important industry in any country, so most airlines were either completely state-owned or had a controlling state stake. But in this case, the airlines were guided in their activities not only by economic, but also by political considerations. The state also regulated the activities of small airlines that were in the hands of private owners. The means of regulation were the appointment of the carrier to perform flights on any route and the establishment of tariffs for air transportation. The innovators in the field of civil aviation liberalization were the United States, which in 1976 adopted the Air Transport Deregulation Act, according to which airlines could independently set tariffs. Market price changes have led many carriers to the need to develop models for analyzing the competitive situation, including flexible tariff levels.
