On September 8, 2026, a software failure at the UK air traffic control provider NATS disrupted operations at multiple UK airports, resulting in the cancellation of more than 1,750 flights. Hundreds of thousands of passengers were stranded across the UK, with significant delays and cancellations also reported by several European airlines.
UK Civil Aviation Authority Initiates Independent Review
The UK Civil Aviation Authority (CAA) announced an independent review of the NATS software failure to investigate the causes and assess the impact on travelers and airlines. This marks the second occasion in three years that the CAA has launched a major review of a NATS systems failure. The
initial report is expected by January 31, 2027, with a final report due by March 8, 2027.
Transport Secretary Demands Accountability and Action
UK Transport Secretary Heidi Alexander called for clear explanations and remedial measures following the incident. She stated, “In recent weeks, passengers and airlines have been let down too many times, and I’m determined to get to the bottom of why.” A spokesperson for NATS confirmed the company would fully cooperate with the regulator’s investigation.
Airline Reactions and Leadership Calls
Ryanair, impacted by the operational disruptions, has repeatedly urged for the resignation of NATS CEO Martin Rolfe. The airline’s criticism follows the widespread cancellations and delays caused by the
system failure on September 8.
The CAA’s review will also evaluate NATS’ plans for system renewal, replacement, and modernization of its critical operational platforms. It aims to verify the implementation of previous recommendations and incorporate lessons from international best practices in air traffic control.
