On 2 October 2007, the United Kingdom and Singapore signed an agreement which, from 30 March 2018, allowed unlimited rights to the 7th freedom and a full exchange of other freedoms of air. Air freedom is a set of commercial air traffic rights that allow one country`s airlines to be in another country`s airspace. They were formulated as a result of differences of opinion on the extent of the liberalization of air transport in the 1944 Convention on International Civil Aviation, known as the Chicago Convention. The United States had requested the negotiation of a standardized set of separate air rights between member states, but most other countries feared that the size of U.S. airlines would dominate air traffic if there were no strict rules. Air freedoms are essential elements of the international network of commercial airways. The use of the terms “freedom” and “right” confers the right to operate international air services only within the multilateral and bilateral agreements (air agreements) that allow it. 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 A country that grants transit fees may charge a fee for the privilege. The adequacy of these royalties has sometimes been controversial. 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.  The fifth freedom of movement is sought by airlines wishing to use unserved or underserved routes or by airlines whose flights already make technical stops in one place, as permitted by the second freedom. :32 governments (z.B.
