Planemakers Poised for Iranian Buying Spree If Nuclear Deal Reached

Western planemakers look set to reap billions of dollars in deals with Iran, if a deal is done on its nuclear program. Successful negotiations would allow one of the world's most promising aviation markets to come out of quarantine. Iran and six world powers were struggling on Friday to remove the last obstacles to an historic deal in Vienna that could resolve a more than 12-year dispute over Tehran's nuclear ambitions. They extended talks through the weekend. For Tehran the removal of sanctions and a US trade embargo may would give them the opportunity to renew a fleet whose average age is almost twice the international average without having to pay steep fees at the black market.
