The first freedom is the right to fly over a foreign country without landing. :31 It grants the privilege of flying over the territory of a contract country without landing. Member States of the International Air Transit Agreement grant this freedom (as well as second freedom) to other Member States, subject to transit aircraft using certain routes.  In the summer of 2007, 129 countries were contracting parties to the treaty, including countries as important as the United States, India and Australia. However, Brazil, Russia, Indonesia and China never rallied, Canada left the treaty in 1988.  These strategically located non-IASTA states prefer to control foreign airlines more strictly overflight in their airspace and negotiate transit agreements with other countries on a case-by-case basis. :23 During the Cold War, the Soviet Union and China did not allow airlines to enter their airspace. There have been flights from Europe to Japan that have been refuelled in Alaska. Since the end of the Cold War, the first freedoms have been almost entirely universal. :151 Most countries require prior notification before an overflight and costs that can sometimes be significant.
 The first and second freedom confer the right to cross a country without carrying traffic that develops or stops there and is called “transit rights”. :146 The Chicago Convention developed a multilateral agreement in which the first two freedoms, the International Air Services Transit Agreement (IASTA) or “Two Freedoms Agreement,” were open to all signatories. In mid-2007, the treaty was adopted by 129 countries.  On 2 October 2007, the United Kingdom and Singapore signed an agreement which, from 30 March 2018, allowed the full exchange of other air freedoms. The eighth unofficial freedom is the right to transport passengers or cargo between two or more points in a foreign country and is also called cabotage. :31 Outside Europe, this is extremely rare. The most important example is the European Union, where such rights exist among all its Member States. The Internal Aviation Market (SAM) was established in 1996 between Australia and New Zealand; the 2001 Protocol to the Multilateral Agreement on the Liberalization of International Air Transport (MALIAT) between Brunei, Chile, New Zealand and Singapore; United Airlines` Island Hopper route from Guam to Honolulu can carry passengers within the Federated States of Micronesia and the Marshall Islands, although the countries involved are closely linked to the United States. In general, these rights have only been granted when the national air network is very underdeveloped.
A remarkable example was the authority of Pan Ams, from the 1950s to the 1980s between Frankfurt and West Berlin, although political circumstances, not the state of the national air network, dictated it – only the allied airlines of France, the United Kingdom and the United States had the right to route air traffic between West Germany and the legally separate and separate area of West Berlin until 1990.  In 2005, the United Kingdom and New Zealand entered into an agreement granting unlimited coasting rights.  Given the distance between the two countries, the agreement can be seen as an expression of a political principle rather than as the expectation that those rights will be invoked in the near future. Similarly, in 1999, New Zealand exchanged eighth freedom rights with Ireland.  Since air services agreements are essentially mercantilist negotiations aimed at a fair exchange of traffic rights, the outcome of a bilateral agreement cannot be entirely reciprocal, but rather reflects the relative size and geographical location of two markets, particularly in the case of a large country negotiating with a much smaller country. :129 In exchange for a smaller state that granted the rights of five freedoms to a larger country, the smaller country might be able to attract transport to the other land towards the goals of sixth freedom. : 129-130 International Air Services Agreement refers to a multilateral agreement signed by members of the Chicago Convention, namely.dem
