Heathrow chaos and misery for travelers
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
A UK air-traffic control glitch cancelled over 2,000 flights in two days, stranding tens of thousands.
The disruption centered on Heathrow, one of the world's busiest hubs, and recovery will.
Background
A technical failure in the UK's National Air Traffic Services (NATS) system on Tuesday upended operations at airports including Heathrow and Gatwick, forcing mass cancellations. NATS described it as a "system issue" and said it was working to resolve the disruption, calling the recovery "very complex." The incident follows a similar technical glitch in July last year and a 2023 air systems failure that affected more than 700,000 passengers.
How it unfolded
- Sep 8, 2026A technical glitch in the NATS air-traffic control system disrupted UK airports including Heathrow and Gatwick, cancelling flights to and from the UK.
- Sep 9, 2026More than 150 flights were scrapped across the country as NATS scrambled to recover; FlightRadar24 reported 177 cancellations for Wednesday, nearly all at Heathrow.
- Sep 10, 2026Nearly 400 flights were scrapped across the UK over the disruption; British Airways said it cancelled nearly 550 flights, affecting 85,000 customers, and a cyberattack was ruled out.
Who’s saying what
- Official
- NATS said it was still working to resolve disruption following a "system issue," calling it a "very complex recovery" that "will take time to recover."

Still unverified
Some reports cite differing cancellation figures (e.g., 250 flights axed vs. 177), and the exact cause of the NATS "system issue" has not been detailed; a cyberattack has been ruled out.
