Aviation regimes generally consist of a treaty-level air services agreement, supplemented by agreements between aviation authorities such as Memorandums of Understanding and/or exchange of letters. It is the australian government`s practice to publish all treaty-level agreements. However, rules with a lower status than the contract are generally not published, as they are traditionally considered confidential between aviation authorities. One of the first AAS after World War II was the Bermuda Agreement, signed in 1946 by the United Kingdom and the United States. The characteristics of this agreement have become models for the thousands of agreements that were to follow, although in recent decades some of the traditional clauses of these agreements have been amended (or "liberalized") in accordance with the "open skies" policy of some governments, particularly the United States.  An air services agreement (also known as the ATA or ASA) is a bilateral agreement that allows international air services between signatories. Since 1992, the Ministry has adopted an "open skies" policy to eliminate government involvement in airline decision-making in international markets through routes, capacity and pricing. Outdoor agreements also contain provisions for business opportunities, security and security. The United States has negotiated "open skies" agreements with more than 100 aviation partners. - negotiating uniform "horizontal" agreements with the Commission on the mandate of EU Member States. Each "horizontal" agreement aims to amend the relevant provisions of all existing bilateral ASAs as part of a single negotiation with a third country. If an agreement does not contain the EU designation clause (all EU air carriers based in the territory of the EU Member State concerned have the opportunity to apply for available traffic rights), this would be contrary to the objectives of this common policy.
In violation of the principle of freedom of establishment set out in Article 49 of the TFUE, such an agreement would continue to discriminate against EU companies on the basis of their nationality.
