WASHINGTON (Reuters) - Boeing ( BA ) said late on Tuesday it has resumed production of all airplane programs that had been halted by a machinists strike in the Pacific Northwest.

The planemaker had confirmed last week it restarted production of its best-selling 737 MAX jetliner in early December - about a month after the end of a seven-week strike by 33,000 factory workers.

Boeing Commercial Airplanes CEO Stephanie Pope said in a social media post on Tuesday the company has "now resumed production across our 737, 767, and 777/777X airplane programs.... We have taken time to ensure all manufacturing teammates are current on training and certifications, while positioning inventory at the optimal levels for smooth production."
