UK Air Traffic Control Glitch Disrupts Flights for Thousands

In early September 2026, a technical failure in the UK's air traffic control system caused massive disruption at British airports. On September 9 alone, 177 flights were cancelled, and over two days, more than 1,400 flights were axed, according to Flightradar24. Airlines such as Singapore Airlines (SIA) had to cancel two flights and divert two others, while Etihad was also affected. The glitch led to long delays and frustration for travelers, with airports warning that disruptions would continue even after flights resumed.
