Just three weeks after a software defect paralysed air traffic control on 8 September, National Air Traffic Services (NATS) admitted to ‘further technical issues’ on 21–22 September that again forced restrictions across UK airspace. According to travel-management platform TravelApp, more than 450 flights were delayed or cancelled at airports from Edinburgh to Gatwick, with knock-on effects still cascading on 23 September. Although the latest outage was resolved within six hours, airlines struggled to reposition crews and aircraft already stretched by summer industrial action. Corporate travel managers report average fare increases of 18 % on key domestic routes and widespread loss of same-day connections to the US and Europe—critical for short-notice client meetings. Under EU261 rules (still retained in UK law), travellers are unlikely to receive compensation because the defect sits with NATS, a third-party provider viewed as an ‘extraordinary circumstance’. However, duty-of-care obligations remain, and several FTSE-100 firms told TravelApp they have triggered emergency accommodation and welfare protocols for stranded employees. The Civil Aviation Authority has demanded a full incident report and is considering whether NATS’ redundancy arrangements meet required resilience standards. Businesses can expect further parliamentary scrutiny, with the Commons Transport Committee scheduling an evidence session for early October. Mobility teams should review contingency plans for time-sensitive assignments and consider alternative routings via continental hubs until confidence in NATS systems is fully restored.
