How big were those losses? If we subtract the $3 billion in charges for the 777X and 767 programs from the $4 billion total loss at the commercial airplanes division, this implies the strike cost Boeing $1 billion in Q3 from sales lost during the strike. This further implies that strike-related losses will cost Boeing another $2 billion in Q4.

Striking Boeing machinists started returning to work on Wednesday after voting for a new contract with substantial wage increases. The 33,000 Seattle-area machinists voted 59 percent to accept, just two weeks after two-thirds of them voted to reject a slightly worse contract.
