Airline CEOs at a major industry event revealed that newer, more fuel-efficient airplane engines are less reliable than promised, requiring earlier and more frequent maintenance. This reduces the expected cost savings from fuel efficiency and increases operational expenses amid rising fuel prices. Engine makers like GE Aerospace acknowledge the issues and are working on improvements, but supply constraints and maintenance challenges persist, impacting airline profitability and fleet availability. The situation highlights ongoing struggles in the aviation sector to balance innovation with reliability and cost control.
