Boeing Co will deliver the first 787 Dreamliner to the Middle East region in the second-quarter of 2012, starting with Qatar Airways, Boeing's president for Middle East and North Africa said. Next in line for deliveries will be Royal Jordanian, followed by Abu Dhabi's Etihad Airways, Jeff Johnson told B loomberg News in an interview in Doha on Wednesday. Boeing has postponed deliveries of its 787 Dreamliner seven times, resulting in a three-year delay, after grappling with new materials, engine supply disruptions and other problems. More than 830 of the jets are on order to 55 airlines, including Gulf carriers Qatar Airways, Gulf Air and Amman-based Royal Jordanian. Akbar Al Baker, the CEO of Qatar Airways which has 30 787s on order and an option for 30 more, said in December he would consider cancelling the order if there were further delays in the plane's delivery.
