Ryanair's CEO, Michael O'Leary, expressed frustration over significant delays in aircraft deliveries from Boeing, which are expected to cause the airline to transport five million fewer passengers this year than initially forecasted. The delays stem from various technical problems at Boeing, resulting in a projected revenue loss of around 500 million euros ($550 million). Ryanair currently has 350 Boeing 737s on order but has seen a sharp decline in the number of aircraft received, leading to further operational challenges. O'Leary criticized Boeing's new management for their continued underperformance and warned that the airline may only receive 20 to 25 of the 737 MAX aircraft ahead of next summer, down from the expected 29. Additionally, the airline has faced a 15% drop in ticket prices, impacting its financial performance, though O'Leary noted that this trend is starting to stabilize. He highlighted the ongoing uncertainties regarding aircraft certification timelines and the overall production issues at Boeing.
