Boeing ($BA@US) has announced plans to increase its output of 737 Max planes to 38 per month from 31, despite a production issue affecting some aircraft. The company is also planning to raise the output of its 787 Dreamliner to five planes per month later this year, up from a current rate of three. Boeing's revenue jumped 28 percent year-over-year, and the company narrowed its net loss to $425 million, or 69 cents per share, from a year-ago net loss of $1.24 billion, or $2.06 per share. The pace of deliveries is crucial to its cash flow goals since customers pay for the bulk of the planes upon delivery.
