DUBAI: Dubai's Emirates unveiled a provisional order for 40 Boeing BA.N 787-10 jetliners, worth $12.5 billion at list prices, at the Dubai Airshow on Sunday.

Emirates chairman, Sheikh Ahmed bin Saeed al-Maktoum, said the carrier had chosen the latest version of Boeing's mid-sized wide-body jet after comparing it with the Airbus . 

Deliveries will start in 2022, he added.

Reuters earlier reported that Boeing was close to clinching a deal for around 40 of the 787-10 jets.
