Boeing's commercial airplane division expects to cut 5,000 jobs next year.
Spokesman Bill Cogswell says most of the reductions will come in the Puget Sound area. Boeing builds its jetliners at factories in Everett and Renton, Washington.
The chief executive of Boeing Commercial Airplanes, Alan Mulally, says the company expects half the cuts to come through attrition and the rest through layoffs.
Cogswell says the exact number of layoffs depends on the company maintaining its typical flur percent to five percent attrition rate.
He says first notices will go out on Friday, and take effect Jan.24.
A Boeing spokesperson in Wichita says he does not expect dramatic layoffs in Wichita next year.
