Ryanair CEO Michael O'Leary has called for the resignation of Martin Rolfe, the chief executive of UK air traffic control provider NATS, following significant flight disruptions at London Gatwick Airport due to staff shortages. The chaos affected over 500 flights, with 57 cancellations and numerous delays, impacting around 16,000 passengers. O'Leary criticized NATS for repeated failures, referencing previous disruptions during last year's August Bank Holiday. He urged the new UK Transport Secretary, Louise Haigh, to intervene if Rolfe does not resign. Gatwick officials acknowledged the staffing issues but highlighted improvements in air traffic control personnel. NATS expressed regret over the disruptions and emphasized ongoing efforts to enhance service reliability.
