Ryanair's Chief Executive Michael O'Leary has expressed frustration with Boeing's management over significant delays in the delivery of 737 MAX aircraft, which are impacting the airline's growth plans and potentially costing them 500 million euros in revenue due to fewer passenger numbers. Ryanair was scheduled to receive 29 aircraft by next summer but now expects only 20 to 25, with recent deliveries falling short of expectations in July and August. The airline also plans to cut services at Berlin's BER airport by 20% starting summer 2025 due to high access costs, affecting six destinations and potentially leading to job losses. While O'Leary noted that ticket prices are expected to decline less than initially forecasted, analysts predict that Ryanair may underperform compared to competitors like easyJet and British Airways. Boeing's production issues, which have persisted since the grounding of the 737 MAX fleet, continue to strain the relationship between the two companies. Despite these challenges, Ryanair remains committed to its order of MAX 10 jets, although certification timelines remain uncertain.
