Bilateral Air Transport Agreement
From Wikipedia, the free encyclopedia
A bilateral Air Transport Agreement (also sometimes called a bilateral Air Service Agreement) is an agreement which two nations sign to allow civil aviation between their territories.
The first ATA is called the Bermuda Agreement, and it was signed in 1946 between the United Kingdom and the United States.
A current model for ATAs is the US introduced Open skies treaty.
In principle all ATAs should be registered by the International Civil Aviation Organization in DAGMAR.
