For the second time in a fortnight, a technical fault at the UK’s National Air Traffic Services (NATS) centre in Prestwick disrupted hundreds of flights on 21 September, with knock-on effects for services linking Scotland and northern England to Paris Charles-de-Gaulle and Lyon. Aviation analytics firm Cirium counted more than 200 cancellations by mid-afternoon, while passengers heading for Disneyland Paris recounted missed connections. Although London airports were “broadly unaffected”, easyJet, British Airways and Air France all cancelled or delayed flights to France from Edinburgh, Glasgow and Manchester. Rail-and-fly passengers found themselves rerouted via Eurostar or rebooked for the following day, triggering accommodation claims under EU Regulation 261. From a mobility-programme standpoint, the glitch highlights the brittleness of cross-Channel itineraries that rely on tight same-day connections. HR teams are advised to remind travelling employees that French rail strikes planned for 22–23 September (unrelated to the aviation issue) may complicate re-routing options. NATS says the root cause was unrelated to the millisecond-timing software bug blamed for a wider UK-wide outage in early September, but UK carriers have demanded an independent review. French aviation authorities are monitoring the situation; a senior DGAC official told AFP that any repeat during the October holidays could overload Paris ATC sectors as airlines file re-routes to avoid UK airspace. While Monday’s disruption was largely resolved by evening, travel-management companies recommend building longer layovers for itineraries that connect via the UK to French regional airports until confidence in NATS systems is restored.
