DUBAI (Reuters) - 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 <AIR.PA> A350.


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.
