Since 1992, the Ministry has adopted an “open skies” policy to eliminate government involvement in airline decision-making in international markets through routes, capacity and pricing. Outdoor agreements also contain provisions for business opportunities, security and security. The United States has negotiated “open skies” agreements with more than 100 aviation partners. The Philippines and Vietnam have recently concluded open skies agreements with other countries. The Philippines signed its first agreement in 2016, when it joined the ASEAN Open Skies Policy for Southeast Asian countries.  The country is improving the quality of its air service to meet increased international competition.  Vietnam joined the ASEAN Open Skies in 2015 and its passenger and freight markets are expected to continue to grow due to increased demand and investment in additional airport capacity.  No public information has been drawn from the ongoing negotiations between the United States, the Philippines and Vietnam.  The United States does not have an open skies agreement with several Asian countries, including China, Vietnam and the Philippines. In the case of China, the United States signed a protocol on off-air air travel in 2007, which contains restrictions on frequencies and code-sharing.
 His language consolidated what the researchers described as “the most liberal and flexible bilateral transportation regime” in China.  Australia was quick to follow suit and signed an open skies agreement with China at the end of 2016. The first “open skies” agreement was concluded in 1992 between the United States and the Netherlands. Since then, agreements have multiplied; the United States now has agreements with 120 other countries. In addition to the bilateral open skies agreements, the United States has negotiated two multilateral open skies agreements: a remarkable trend is the conclusion of bilateral open skies agreements that provide unrestricted access to third-party, fourth and fifth freedom, designation, capacity, frequencies, code-sharing and tariffs. The first such agreement was concluded in 1992 between the Netherlands and the United States. Since then, more and more open-ski agreements (OSAs) have been signed. In September 2016, more than 300 OSA were closed with more than 150 countries, with the United States leading the way with a total of 119 OSA signed. More and more countries have also signed OSA with the European Union or its members. Airline alliances are cooperation agreements between U.S.
and foreign airlines that enter into limited marketing agreements, such as a mutual loyalty program. B or an international code-sharing agreement allowing an airline to sell seats on a partner`s planes as if they were its own.  Alliances facilitate international air traffic for passengers and provide smooth flights between cities that would otherwise not have non-stop service on the same airline. To form these alliances, airlines need U.S. Department of Transportation(DOT) antitrust immunity (ATI) and an open skies agreement or similar type of agreement (such as the 2007 Sino-U.S. agreement) with the foreign airline`s home country is an essential condition for obtaining the ITA grant.  The obstacle to a comprehensive bilateral open skies agreement between the United States and China boils down to slots for aircraft at airports. Currently, there are restrictions on the number of U.S. flights.
