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 Unlike shipping rights, „trafficking rights” allow international commercial services between, by and in some cases, within countries that are parties to air agreements or other contracts.  While it was agreed that the third to fifth freedom should be negotiated between states, the international agreement on air services (or „five freedoms agreement”) was also opened for signature, which includes the first five freedoms. :108 The other four freedoms are made possible by certain air agreements, but not „officially” because they are not mentioned in the Chicago Convention. 108 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.  Freedom of the air is a set of commercial aviation rights authorized to grant the right to one country`s airlines and land 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.
