• Boeing is projected to report a third-quarter loss of approximately $153 million.
• The company delivered 161 commercial aircraft during the third quarter.
• Production challenges continue for 737 and 787 aircraft.
• Analysts focus on Boeing's cash flow, under pressure from spending on 777-9 certification.

This expected loss may indicate ongoing challenges for Boeing in stabilizing production and managing cash flow, which could impact its competitive position in the commercial aviation market. The recent certification milestones and increased deliveries suggest a positive trend, but the company's ability to sustain this momentum may be crucial to its long-term success.
