Boeing warns Seattle could lose 777X if deal rejected

Boeing said on Friday it was ready to re-examine alternative sites for its newest jet if assembly workers and local politicians do not ratify plans to build it in the Seattle area, its traditional manufacturing base.

The U.S. planemaker issued the warning hours after senior members of the International Association of Machinists union were reported to voice opposition to a proposed labour contract that is due to go to a membership vote next Wednesday.
