First freedom

The first freedom is the right to fly over a foreign country without landing. It is also known as the technical freedom. 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 of America, India

. However, Brazil, Russia, Indonesia, and China never joined, and Canada left 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.

Since the end of the Cold War
Cold War
The Cold War was the continuing state from roughly 1946 to 1991 of political conflict, military tension, proxy wars, and economic competition between the Communist World—primarily the Soviet Union and its satellite states and allies—and the powers of the Western world, primarily the United States...

, first freedom rights are almost completely universal, although most countries require prior notification before an overflight, and charge substantial fees for the privilege.

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 IASTA, 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. For example, the Federal Aviation Administration

 of the U.S., an IASTA signatory, as of 2009 charges the so-called enroute fees, of US$33.72 per 100 nautical miles (185.2 km), of great circle distance from point of entry of an aircraft into the U.S.-controlled airspace to the point of its exit from this airspace. In addition, a lower fee (a so-called oceanic fee) of $15.94 per 100 nautical miles (185.2 km) is charged for flying over the international waters where air traffic is controlled by the U.S., which includes sections of Pacific, Atlantic, and Arctic Oceans. 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, which cross Siberia.

Second freedom

The second freedom allows technical stops without the embarking or disembarking of passengers or cargo. It is the right to stop in one country solely for refueling or other maintenance on the way to another country.

The most famous example of the second freedom is Shannon Airport
Shannon Airport
Shannon Airport, is one of the Republic of Ireland's three primary airports along with Dublin and Cork. In 2010 around 1,750,000 passengers passed through the airport, making it the third busiest airport in the Republic of Ireland after Dublin and Cork, and the fifth busiest airport on the island...

 was also a frequent stopping point for airlines from the USSR and East Germany on the way to the Caribbean, Central America, Mexico and South America.

Because of longer range of modern airliners, second freedom rights are comparatively rarely exercised by passenger carriers today, but they are widely used by air cargo carriers, and are more or less universal between countries.

Third freedom

The third freedom is the right to carry passengers or cargo from one's own country to another.

The third freedom was the first commercial freedom.

Fourth freedom

The right to carry passengers or cargo from another country to one's own is the fourth freedom.

Third and fourth freedom rights are almost always granted simultaneously in bilateral agreements between countries.

Fifth freedom

The fifth freedom, also referred to as beyond rights
Beyond rights
Beyond rights is another name for the Fifth Freedom of air travel, as defined by the Convention on International Civil Aviation in 1944, otherwise known as the Chicago Convention....

, allows an airline to carry revenue traffic between foreign countries as a part of services connecting the airline's own country. It is the right to carry passengers from one's own country to a second country, and from that country to a third country (and so on). The "unofficial 'seventh freedom'", is a variation of the fifth freedom and allows international services wholly outside of an airline's origin. An example of a fifth freedom flight is a 2004 Emirates Airlines flight originating in Dubai, then going on to Brisbane, Australia, and then from Brisbane to Auckland, New Zealand, where tickets can be sold on any or all sectors, and in the reverse direction if flights are offered.

Fifth Freedom rights were instrumental to the economic viability of long-haul flight until the early 1980s when advances in technology and increases in passenger volume allowed the introduction of more non-stop

. Fifth freedom rights are also sought by airlines wishing to take up unserved and underserved routes, or those airlines whose flights already make technical stops at a location as allowed by the second freedom.

Sixth freedom

The unofficial sixth freedom combines the third freedom and fourth freedoms and is the right to carry passengers or cargo from a second country to a third country by stopping in one's own country.

Seventh freedom

The unofficial seventh freedom is a variation of the fifth freedom. It is the right to carry passengers or cargo between two foreign countries without any continuing service to one's own country.

The seventh freedom is rare because it is usually not in the commercial interest of airlines, except in Europe where an EU open sky has seen many carriers, particularly low cost carriers, operate flights between two points, with neither of them being in their home country. Ryanair

 has a wide variety of such routes. On 2 October 2007, the United Kingdom and Singapore signed an agreement that will allow unlimited seventh freedom rights from 30 March 2008 (along with a full exchange of other freedoms of the air).

Eighth freedom (consecutive cabotage)

The unofficial eighth freedom is the right to carry passengers or cargo between two or more points in one foreign country and is also known as cabotage
