Aviation Bilateral Agreements
An air services agreement (also known as the ATA or ASA) is a bilateral agreement that allows international commercial air services between signatories. 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. 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.  The ASA covers the basic framework under which airlines obtain bilateral economic flight rights in two countries. Frequency, designated airlines of the two signatory states, points of origin and intermediate points, traffic rights, type of aircraft and tax issues are generally covered by soft. Horizontal negotiation method: changes with 41 countries and a regional organisation of 8 Member States, representing 670 other bilateral agreements. The latter has the advantages of simplicity, cost efficiency and time.
BASA covers a wide range of aviation sectors, including aircraft maintenance, air operations and environmental certification. The bilateral system is based on the Chicago Convention and related multilateral treaties. The Chicago Convention was signed in December 1944 and has governed international air services ever since. the convention also contains a number of annexes covering issues such as aviation safety, safety monitoring, seaworthiness, navigation, environmental protection and facilities (acceleration and departure at airports). In 1913, a bilateral exchange of notes  between Germany and France was signed in the first agreement to provide airship services. A bilateral air services agreement is reached between two states parties, which liberalizes commercial civil aviation services between these countries. Bilateral air services agreements allow designated airlines in these countries to operate commercial flights covering passenger and cargo transport between the two countries. In addition, they generally regulate the frequency and capacity of air services between countries, pricing and other commercial aspects. – 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. In 1944, when World War II was in the final stages, 54 countries came to the conference in Chicago, USA, to talk about the future of international aviation. The conference resulted in the signing of the International Civil Aviation Convention, commonly known as the Chicago Convention.
The Chicago Convention defined the rules governing international air travel activity. In addition, the International Civil Aviation Organization (ICAO), the United Nations organization responsible for the planning and development of international air transport (ICAO, 2011)1. Note: EU external air transport policy: why does the EU want to change air agreements between its member states and partner countries? – bilateral negotiations between each EU member state concerned and its partners with a view to separately amending the bilateral aviation security agreements (ASA), the bilateral aviation security agreements (BASA) provide for technical cooperation between FAA and other civil aviation authorities.
