Boeing has appointed new heads of its business in Qatar and Turkey, the U.S. aerospace giant said on Wednesday. Omar Arekat becomes managing director for Qatar in addition to his current role as Boeing Commercial Airplanes sales director, while Ayem Sargn Il has been named managing director of Boeing Turkey. These changes follow Bernie Dunn's appointment as president of Boeing's Middle East business in May - he had previously been in charge of Turkey and North Africa.
