Emirates orders 40 Boeing jets

Emirates has unveiled a preliminary order worth $15 billion for 40 Boeing jets. It wasn't the only blow for Boeing's rival Airbus ahead of a key air show in Dubai. Deliveries will start in 2022 and Emirates is yet to decide between engines offered by General Electric and Rolls-Royce. Dubai wants a guarantee that Airbus will keep production of the aircraft open for at least 10 years.
