CHICAGO - Boeing has booked a big order for its planned 777X aircraft.
Hong Kong airline Cathay Pacific is buying 21 of the planes, which Boeing will build later this decade.
The 777X will be an updated version of Boeing's bestselling 777. That is Boeing's second-biggest plane, used by airlines for very long international flights. For the new version, Boeing plans to replace its aluminum wings with wings made from a lightweight, high-tech plastic, and make other improvements that will make the plane more fuel-efficient.
