Overview
- A technical fault in NATS' flight‑processing system on Tuesday caused network‑wide disruption that led to roughly 2,000 cancellations and affected about 330,000 passengers while core services were later restored.
- Transport Secretary Heidi Alexander has told NATS CEO Martin Rolfe to deliver a written investigation within seven days and has asked the Civil Aviation Authority to run a separate independent review with findings due in six months.
- Airlines including Ryanair and Wizz Air publicly called for Rolfe to resign and have criticised NATS' investment choices, while Ryanair continues legal action over the 2023 outage.
- Reporting since the incident has highlighted NATS' ageing technology and maintenance practices, including legacy codebases and bolted‑on front ends, and has questioned whether past reinvestment and contingency measures were adequate.
- Passengers face limited compensation because the CAA may classify the failure as 'extraordinary circumstances'; airports and airlines are still working through a large recovery backlog with knock‑on delays for days ahead.
