As Boeing Co. lurches from one crisis to the next, there’s been one constant for the embattled planemaker: Its predicament appears to be only getting worse.

Boeing Co.’s cash surged last quarter as it restarted 787 Dreamliner deliveries after a lengthy halt, giving investors a glimpse of the bounty that awaits as the manufacturer clears hundreds of undelivered aircraft from its storage lots.

United Airlines Holdings Inc. is closing in on an order for more than 100 widebody jets as it studies offers for Boeing Co.’s 787 Dreamliner and Airbus SE’s A350, according to people briefed on the matter.

Boeing Co. generated $81 million in cash from its operations during the second quarter, sharply reversing its heavy cash use earlier this year as the planemaker stepped up deliveries of its highly profitable 737 Max jetliners.

Dave Calhoun was brought in as Boeing Co.’s chief executive officer to steer it through a crisis that unfurled after the crashes of two of its 737 Max jets.
