An open skies agreement is a bilateral aviation agreement between two countries that allows airlines from those countries to operate commercial flights between them without any restrictions. This type of agreement allows airlines to fly any route between the two countries, without restrictions on the number of flights or the prices they charge.

Essentially, an open skies agreement creates a free-market environment for airlines to operate international flights, giving them greater freedom and flexibility in terms of routes, schedules, and pricing. This can result in increased competition, lower fares, and more options for travelers.

Open skies agreements also typically include provisions for safety and security standards, as well as rules for air traffic control and other operational aspects of international flights. This helps ensure that both countries` interests and priorities are protected.

The first open skies agreement was signed between the United States and the Netherlands in 1992, and since then, many other countries have signed similar agreements, including the European Union, Canada, and Japan.

Overall, open skies agreements are beneficial for both airlines and travelers, as they promote competition and consumer choice, while also ensuring safety and security standards are upheld. These agreements are an important tool for promoting international trade and economic growth, as well as fostering strong relationships between countries.
