The aim of the paper is to present the process of liberalization of international regulations of aviation market. Since the mid 90-s there has been a considerable development of transport market and aviation industry. One can observe a significant progress towards liberalization of regulations of international aviation transport. There is also a growing number of states which are the parties in the contacts of full market access. At the same time the aviation industry is going through structural transformations such as mergers and alliances which enables companies to compete on the world's aviation market. The authoress analyses the activities of international organizations (ICAO) and regional organizations (the EU) with reference to existing problems on the aviation market ( privatization, commercialization, property, control ) She points out that in the times of liberalization of regulations of the industry globalization and the era of aviation alliances the time has come to loosen the regulations concerning foreign investment addressed to national carriers. The trends existing in economy indicate the international character of markets in a lot of essential areas. Transgenic flows of capital coincide with a huge increase in the number of multinational companies which join the capital and introduce mixed boards consisting of different states citizens. Currently there is a large number of companies which do not possess a clear cut line of division of national responsibilities. The authoress concludes that aviation widely understood as 'airline industry' will also be susceptible to these trends and will gradually lose its national character. The beginning of these changes in recent years has been a gradual liberalization of aviation transport in Europe and opening competition among aviation carriers in other regions of the world, such as Australia and New Zealand.
