Two SIA Flights Diverted as Heathrow Hit by Major Outage 1,300 Cancellations Cause Chaos at UK's Busiest Airport

Two Singapore Airlines flights from Singapore to London were diverted on Tuesday after a major technical failure at NATS, the UK's air traffic control provider, forced Heathrow to halt arrivals and sparked the cancellation of over 1,300 flights across the UK.

Two Singapore Airlines flights from Singapore to London were forced to divert on Tuesday as a major technical failure at the UK's National Air Traffic Services brought Heathrow Airport to a standstill, causing widespread disruption across the country.

NATS Technical Failure Triggers Chaos

The disruption began on Tuesday when a "very complex" technical problem affected NATS' flight processing system at a facility in the UK. The issues severely reduced the ability to process and manage flights efficiently. NATS confirmed the system had been fixed but warned that recovery would "take time."  According to flight-tracking data, over 1,300 flights to and from UK airports were cancelled on Tuesday, with another 177 cancelled on Wednesday nearly all of them at Heathrow. Airline-specific impacts included 218 easy Jet flights, 132 British Airways flights, 41 Ryanair flights, 37 KLM flights and 22 Eurowings flights. Ryanair said more than 65,000 of its passengers were affected.

SIA Flights Diverted

Two SIA flights from Singapore to London were among those affected by the outage. Singapore Airlines flights SQ318 and SQ322 were diverted to other European airports. The diversions came as Heathrow advised passengers not to travel to the airport unless their flight was confirmed, with departures resuming later on Tuesday evening but arrivals remaining suspended.

Backlash against NATS

The outage has triggered sharp criticism from airlines, with Ryanair calling for NATS chief executive Martin Rolfe to resign. The airline noted that the latest incident shows "nothing has changed" since a catastrophic NATS failure in 2023 that affected more than 700,000 passengers. The UK Transport Secretary has summoned NATS CEO Martin Rolfe, who has accepted "full responsibility" for the incident.

Here is the question this outage raises. A technical failure at NATS has caused over 1,300 flight cancellations and stranded tens of thousands of passengers, echoing a similar collapse in 2023. When the same critical infrastructure provider fails repeatedly, does this signal a systemic problem in the UK's aviation oversight, or is it simply the cost of managing one of the world's busiest airspaces?
