The first two freedoms concern the passage of commercial aircraft through foreign airspace and airports, while the other freedoms concern the international transport of people, mail and cargo. The first to the fifth freedoms are officially listed by international treaties, especially the Chicago Convention. Several other freedoms have been added and, although most are not officially recognized in international treaties of general application, they have been agreed by a number of countries. The freedoms cited in lower numbers are relatively universal, while the higher numbers are rarer and more controversial. Open-air liberal agreements are often the least restrictive form of air agreements and can encompass many, if not all, freedoms. They are relatively rare, but recent single air transport markets in the European Union (European Aviation Area) and between Australia and New Zealand are examples. The third and fourth freedoms allow a fundamental international service between two countries. 146 Even if reciprocal rights are granted under the third and fourth freedoms, air services agreements (e.g. B Bermuda conventions) can still restrict many aspects of traffic, such as aircraft capacity, frequency of flights, airlines and airports to be served. :146-147 The third freedom is the right to transport passengers or goods from their own country to another.
:31 The right to transport passengers or cargo from another country to one`s own country is the fourth freedom. :31 Third and fourth freedoms are almost always granted simultaneously in bilateral agreements between countries. In addition, the rights also include international flights with a stopover abroad, where passengers can only board and disembark at the intermediate stage of the route that originally serves an airline that serves them. 146 It also includes the “stopover” in which passengers can board or disembark at a stopover as part of an itinerary between the arrival points of a multi-leg flight or connecting flights. Note146 Some international flights stop at several points in a foreign country, and passengers can sometimes make stops in the same way, but because the traffic being transported does not occur in the country where the flight takes place, it is not a matter of coasting, but of another form beyond rights. :110 The eighth unofficial freedom is the right to transport passengers or goods between two or more points in a foreign country and is also known as coasting. :31 Outside Europe, this is extremely rare.
