American airlines reported a $1.1 billion operating profit for the second quarter, a period marked by operational disruption, ongoing litigation with mechanics and a capacity shortfall caused by the Boeing 737 Max grounding. During a second quarter earnings call this morning, chief executive Doug Parker attributed the strong performance to "revenue driven improvement". Revenue was up 2.7% year-over-year to $12 billion – a second quarter record for the carrier – despite the grounding of its 737 Max fleet, weather-related issues and legal action taken against its mechanics union. Executive vice president and chief financial officer Derek Kerr calls the period "undoubtedly a challenging quarter for American". Despite the challenges, the carrier produced "financial results which exceeded expectations". The Fort Worth, Texas-based carrier has revised its capacity growth to 1.5% for the full-year primarily due to the 737 Max being out of service.
