Boeing factory workers held a large rally in Seattle to demand a better wage deal, mounting pressure on new CEO Kelly Ortberg to end a bitter strike that has plunged the planemaker further into financial crisis.

Depending on whom you ask, Boeing is losing anywhere from $1 billion per week (says The Washington Post) to $1 billion per month (says CNBC) as this strike drags on. Prior guesses have ranged as high as $100 million to $150 million per day (which works out to $3 billion to $4.5 billion per month).
