Freedoms of the air
The freedoms of the air, also called five freedoms of air transport, are a set of commercial aviation rights granting a country's airlines the privilege to enter and land in another country's airspace. They were formulated as a result of disagreements over the extent of aviation liberalisation in the Convention on International Civil Aviation of 1944, known as the Chicago Convention. The United States had called for a standardized set of separate air rights to be negotiated between states, but most other countries were concerned that the size of the U.S. airlines would dominate air travel if there were not strict rules. The freedoms of the air are the fundamental building blocks of the international commercial aviation route network. The use of the terms "freedom" and "right" confers entitlement to operate international air services only within the scope of the multilateral and bilateral treaties (air services agreements) that allow them.
The first two freedoms concern the passage of commercial aircraft through foreign airspace and airports, while the other freedoms are about carrying people, mail and cargo internationally. The first through fifth freedoms are officially enumerated by international treaties, especially the Chicago Convention. Several other freedoms have been added, and although most are not officially recognised under broadly applicable international treaties, they have been agreed to by a number of countries. The lower-numbered freedoms are relatively universal while the higher-numbered ones are rarer and more controversial. Liberal open skies agreements often represent the least restrictive form of air services agreements and may include many if not all freedoms. They are relatively rare, but examples include the recent single aviation markets established in the European Union (European Common Aviation Area), and between Australia and New Zealand.
Freedoms of the air apply to commercial aviation. The terms 'freedom' and 'right' are a shorthand way of referring to the type of international services permitted between two or more countries. Even when such services are allowed by countries, airlines may still face restrictions to accessing them by the terms of treaties or for other reasons.
The first and second freedoms grant rights to pass through a country without carrying traffic that originates or terminates there and are known as 'transit rights'. The Chicago Convention drew up a multilateral agreement in which the first two freedoms, known as the International Air Services Transit Agreement (IASTA) or "Two Freedoms Agreement", were open to all signatories. At the end of 2017, the treaty was accepted by 133 countries.
A country granting transit rights may impose fees for the privilege. The reasonableness of such fees has caused controversy at times.
The first freedom is the right to fly over a foreign country without landing. It grants the privilege to fly over the territory of a treaty country without landing. Member states of the International Air Services Transit Agreement grant this freedom (as well as the second freedom) to other member states, subject to the transiting aircraft using designated air routes. As of the summer of 2007, 129 countries were parties to this treaty, including such large ones as the United States, India, and Australia. However, Brazil, Russia, Indonesia, and China never joined, with Canada leaving the treaty in 1988. These large and strategically located non-IASTA-member states prefer to maintain tighter control over foreign airlines' overflight of their airspace and negotiate transit agreements with other countries on a case-by-case basis. During the Cold War, the Soviet Union and China did not allow airlines to enter their airspace.[citation needed] There were flights from Europe to Japan that refueled in Alaska. Since the end of the Cold War, first freedom rights are almost completely universal. Most countries require prior notification before an overflight and charge fees, which can sometimes be substantial.
IASTA allows each member country to charge foreign airlines "reasonable" fees for using its airports (which is applicable, presumably, only to the second freedom) and "facilities"; according to IATA, such fees should not be higher than those charged to domestic airlines engaged in similar international services. Such fees indeed are commonly charged merely for the privilege of the overflight of a country's national territory, when no airport usage is involved. (Overflights might still be using services of a country's air traffic control centers). For example, the Federal Aviation Administration of the U.S., an IASTA signatory, charges overflight fees based on the great circle distance between an aircraft's points of entry into and exit from U.S.-controlled airspace. This transit is then divided into overland (referred to as en route) and oceanic components; the latter include flights over international waters where air traffic is controlled by the U.S., including sections of Atlantic and Arctic Oceans and much of the northern Pacific Ocean. Since 2019 these have been charged at $0.6175/nmi ($0.3334/km; $0.5366/mi) for en route components, and $0.2651/nmi ($0.1431/km; $0.2304/mi) for the oceanic components.
Countries that are not signatories of the IASTA charge overflight fees as well; among them, Russia is known for charging high fees, especially on the transarctic routes (between North America and Asia) that cross Siberia. In 2008, Russia temporarily denied Lufthansa Cargo permission to overfly its airspace with cargo ostensibly due to "delayed payments for its flyover rights". In 2008, European airlines were paying Russia €300 million a year for flyover permissions.
