The United States and Saudi Arabia initiated an Open Skies agreement, easing air transit red tape between the two nations, the US government said.

"This agreement strengthens and expands our already strong trade and tourism links with Saudi Arabia, and will benefit American and Saudi Arabian businesses and travelers," a statement from the State Department said.

"It will expand air service and encourage vigorous price competition by airlines, while safeguarding aviation safety and security."

Open Skies agreements reduce government involvement in the commercial decisions of air carriers about routes, capacity, and pricing, freeing carriers, and are said to provide more affordable, convenient, and efficient air service for consumers.

They also are credited with promoting travel and trade, spurring job and economic development.

The United States, which has more than a hundred Open Skies agreements with foreign governments, said they have led to vastly expanded international passenger and cargo flights to and from the United States.
