Boeing is awarding $296 million in incentive pay to 51,800 employees in Washington.
Companywide, Boeing is paying more than $624 million to 107,000 employees in the incentive plan based on 2012 financial results.
Boeing said the awards to be paid beginning Thursday equate to a bonus of about 6 percent, or about 15 days of additional pay.
The company said Wednesday the 2012 awards are among the best ever for the plan that began in 2001.
The incentive pay does not go to executives or members of the Machinists Union who have other plans.
