On 2 October 2007, the United Kingdom and Singapore signed an agreement authorising, from 30 March 2018, unlimited seventh freedom rights and a full exchange of other aviation freedoms. Air freedoms are a set of commercial air rights that give airlines of one country the privilege of entering and landing in the airspace of another country. They were formulated following differences of opinion on the extent of the liberalization of air transport in the 1944 Agreement on International Civil Aviation, known as the Chicago Convention. The U.S. 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 U.S. airlines would dominate air traffic if there were no strict rules. Aviation freedoms are the fundamental elements of the international commercial aviation network. The use of the terms „freedom“ and „right“ gives entitlement to the provision of international air services only within the framework of the multilateral and bilateral agreements (air agreements) that they authorize. A country that grants transit rights may collect fees for the privilege. The adequacy of these royalties has sometimes been controversial. The seventh and ninth unofficial freedoms are variations of the fifth freedom.
It is the right to transport passengers or goods to foreign areas without any services to, from or to their country. [6:31 The seventh freedom is to provide international services between two foreign countries, and the ninth between points within a single foreign country. IASTA allows each Member State to charge foreign airlines „reasonable“ charges for the use of their airports (which probably only apply to the second freedom) and „facilities“;  According to IATA, these charges should not exceed those charged to domestic airlines providing similar international services.  Indeed, these charges are generally levied only for the privilege of flying over the national territory of a country if no use of the airport is at stake.  (overflights may still use the services of a country`s air navigation centres). . . .
