Last year was already Boeing's best-ever for cash flow, with S&P Global Market Intelligence data showing that Boeing generated $10.5 billion in positive cash from operations. (Minus $2.6 billion in capital expenditures, free cash flow for the year was $7.9 billion.) But Boeing thinks it can do better this year. According to management's most recent guidance, Boeing should generate "approximately $10.75 billion" cash from operations in 2017.
