Boeing may cut or halt 737 output if return to service delayed

Boeing does not rule out further reducing or temporarily shutting down production of its grounded 737 MAX aircraft if its estimates on the timing of a return to service have to be revised, Chief Executive Dennis Muilenburg said on Wednesday.

Boeing cut production of its best-selling jet by 20 percent in April to 42 a month from 52 a month, weeks after it was grounded worldwide in the wake of two fatal crashes.
