One of the most important aspects of transport and tourism, not only in Europe, but around the world, is the ability to maintain international relations and travel between countries. To ensure open traffic between the United States and Europe, there is what is known as the “open skies” agreement. The initial agreement was signed on April 30, 2007 in Washington, D.C. The agreement entered into force on March 30, 2008. The second phase was signed in June 2010 and has been applied on an interim basis until all signatories are ratified.  The degree of “heavenly openness” depends on the freedoms of the air in the country granted to foreign airlines. Under the 1944 Convention on International Civil Aviation, there are nine such freedoms. The “open skies” treaty is indefinite and open to the accession of other states. The republics of the former Soviet Union (U.S.S.R.), which are not yet contracting parties, can join at any time. Applications from other interested countries are subject to a consensus decision by the Open Skis Advisory Board (OSCC).
 Since it came into force in 2002, eight countries have joined the treaty: Bosnia and Herzegovina, Croatia, Estonia, Finland, Latvia, Lithuania, Slovenia and Sweden. Austria, Cyprus, Ireland, Switzerland, Serbia, Montenegro, Albania, Northern Macedonia, Moldova, Armenia and Uzbekistan are particularly absent. The Republic of Cyprus applied to join the treaty in 2002; But since then, Turkey has blocked its accession. [Citation required] An unknown term, which often appears in the same context, is the word cabotage. Although it was originally referred to the transport of goods or persons between two places within the same country (the word is based on the French coast, which means “navigating a coast”), coasting is now often used to refer to a country`s exclusive right to control air traffic within its borders. In other Central Asian countries, the concept of open skiing is irrelevant. Neutralturkmenistan is not at all interested.
