Boeing forecasts big losses after the Alaska Airlines incident

(CNN)– Boeing will report a massive loss in the first quarter stemming from the Jan.5 Alaska Airlines door plug blowout.

Boeing’s Chief Financial Officer shared the news at an investor conference today.

The company said its commercial airplane unit’s operating profit margin will plunge to around negative 20 percent.

That would be the biggest loss margin for the unit in two years.

The company took a big hit when it was forced to halt delivers of its 787 Dreamliner because of quality issues.
