The second-quarter results of European and American aviation giants Airbus and Boeing were generally better than expected, but the CEOs of both companies pointed out that aircraft manufacturers face a "complex" operating environment. Airbus reported higher-than-expected revenue and profits in the second quarter. Revenue in the first half of the year was lower than expected, but profits were still higher than expected. Airbus kept some of its full-year performance guidance unchanged and still expects adjusted EBIT to be about 6 billion euros, roughly in line with analysts' expectations of 6.06 billion euros. At the same time, Airbus lowered its adjusted free cash flow (FCF) forecast from 4.7 billion euros to 3 billion euros, a decrease of 36%, lower than the 3.32 billion euros expected by analysts. Boeing's second-quarter deliveries were 21% higher than expected and it significantly increased the planned production rate of the 737. Boeing also reiterated full-year free cash flow guidance of $3 billion to $5 billion.
