On 1 May 2001, the United States and Brunei, Chile, New Zealand and Singapore signed a multilateral open-air agreement, known as the Multilateral Agreement on the Liberalization of International Air Transport (MALIAT). The department continues to invite our aviation partners to join MALIAT in order to reach open skis with several partners. Bilateral air services agreements were then extended to multilateral air services agreements. “A multilateral air services agreement is the same as a bilateral air services agreement, the only difference being that it affects more than two states parties” (Wikipedia)4. These agreements subsequently resulted in another form of agreement, known as the “open skies” agreement. This site introduces you to the world of the bilateral air system. It explains that in 1913, a bilateral exchange of notes  between Germany and France was signed as part of the agreement as soon as possible to provide airship services. 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.  Bilateral air services agreements contain provisions for: Bilateral Air Services Agreements (“BASAs”) are contracts signed between countries to enable international commercial air services between zones. The BASA promotes the international air link between countries, which provides and enables the transport of passengers, freight, trade and tourism.
These agreements provide the framework in which the identified airlines of the two countries fly in the designated ports of the other country. It generally deals with issues relating to traffic rights, the use of intermediate links, the nature of aircraft, safety standards, competition, ownership policy, airline design and control, etc., so that both countries can benefit from the agreement, tariffs and tax issues. Air Services Agreements (ASAs) are formal contracts between countries – Memorandums of Understanding (Memorandum of Understanding) and formal diplomatic notes. It is not mandatory to have an ASA for the operation of international services, but cases where contract-free services exist are rare. In the meantime, we are working under the bilateral system to liberalize the air traffic regime and gradually lift restrictions on routes, capacity and ownership of flights.
