DUBAI, U.A.E. - On the first day of the Dubai Airshow, Boeing announced first big sale of the five-day event - with Emirates ordering 40 Boeing 787 Dreamliners in a deal worth about $15 billion at list prices.
Chairman of Emirates, Sheikh Ahmed bin Saeed al-Maktoum, said the aircraft had been chosen over the Airbus A350.
The largest airline in the Middle East, Emirates is already the biggest customer for Boeing's 777, with 165 in service and another 164 on order.
Commenting on the order on Sunday, Sheikh Ahmed said the order raises the cost of its purchase of Boeing aircraft to $90 billion.
According to the company, some of the new 787s will be used to replace older planes, while others will be used to expand the airline's network.
The deal was welcomed by Boeing, which Kevin McAllister, head of its commercial aviation division, said would sustain many jobs in the United States.
The companies said that deliveries of the aircraft are scheduled to start in 2022.
Meanwhile, on the first day of the Dubai Airshow, Azerbaijan Airlines said it was buying five Dreamliners, as well as two Boeing freighters, in a deal worth an estimated $2 billion.
