The Air Services Agreement (ASA), also known as the Air Services Agreement (ATA), is a bilateral or multilateral agreement between states and provides a fundamental framework for the creation of international commercial air services between states. In 1913, a bilateral exchange of notes  between Germany and France was signed in the first agreement 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.  The Department of Civil Aviation is responsible for managing ASA negotiations with other countries to develop our international commercial air services. Airlines operating international air services do so under the capacity requirements that are included in air transportation regimes. The available capacity registry indicates the capacity available to Australian air carriers. The capacity available to foreign airlines during the last planning season is shown in the “Growth Potential for Foreign Airlines” table (PDF: 147 KB). DISCLAIMER The attached documents are internal department working papers, developed for selfish use. This document can only be used as a guide to services authorized and operated under bilateral air services agreements and agreements in Australia. The rights and capabilities negotiated under the bilateral air services agreement and Australia`s agreements are under ongoing review and airlines often change their operations.

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. 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). 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. An air services agreement (also known as the ATA or ASA) is a bilateral agreement that allows international commercial air services between signatories.
