Béteille worked with Air France and Lufthansa, as well as U.S.-based airlines like United, TWA and American Airlines. He also decided that English should be the working language and that measurements should not be metric because most airlines already had American built aircraft.

He is known for the success of Airbus and is sometimes called "Mr. Airbus".[1]
