Chicago - United Airlines added nine Boeing 787-9 Dreamliner to an existing order bringing the total number of its 787-9s on order to 47 (25 in service). The deal is valued at slightly more than $2.5 billion at list prices.

These additional 787-9s will be available from 2020 and will replace older widebodies in United's fleet. Recall that the Star Alliance company also operates twelve 787-8 from the Boeing's Dreamliner family, and will put the first of its 14 787-10 into service next January on transcontinental routes.
