Heathrow Airport Reopening Underway After Massive Fire Disruption

The long-awaited Heathrow Airport reopening has begun following a massive fire that caused a complete shutdown of the UK’s busiest international airport. Thousands of passengers were left stranded across the UK and Europe after a fire at a power substation knocked out electricity at Heathrow late Thursday evening.

Flights gradually resumed on Friday evening, but the full restoration of services will take time. According to Heathrow officials, operations are expected to return to near-normal levels by Saturday, although airlines like British Airways have indicated that not all scheduled flights will run as planned.

The Heathrow Airport reopening comes after what airport chief executive Thomas Woldbye described as one of the most severe incidents the airport has ever faced.

Why Did Heathrow Airport Shut Down?

The unexpected closure was caused by a large fire at an electricity substation in Hayes, West London, near Heathrow. The blaze triggered a complete power outage at the airport, affecting all terminals and ground systems. Backup generators kicked in, but they were not capable of supporting the full scale of operations across Heathrow’s expansive infrastructure.

Speaking to the press, Heathrow CEO Thomas Woldbye said the fire had a catastrophic impact on airport systems. He called it “as big as it gets” in terms of operational disruption and said the incident led to the loss of power comparable to that of a medium-sized city.

Woldbye also emphasized that while contingency systems performed as designed, they were never meant to operate the entire airport.

Flights Resume, But Full Heathrow Airport Reopening Still Pending

Although flights began to resume Friday night, Heathrow had initially declared the airport would remain closed until 11:59 pm. Repatriation flights for passengers stranded in other parts of Europe were prioritized.

British Airways, Air Canada, and United Airlines were among the first carriers to restart partial operations. However, the journey to complete Heathrow Airport reopening will take time, as airline schedules and airport systems still face ongoing adjustments.

On Friday alone, Heathrow was scheduled to manage 1,351 flights with close to 291,000 passengers. Instead, many flights were diverted to other UK airports, and some long-haul services returned to their origin airports. This created a chain reaction of delays and cancellations, impacting travelers across multiple countries.

When Will Heathrow Airport Fully Reopen?

Passengers and industry insiders are asking the critical question: when will Heathrow Airport reopening be complete?

According to Woldbye, Heathrow is targeting 100% operational capacity by Saturday. However, British Airways has announced it expects to operate only 85% of its scheduled flights that day, citing ongoing logistical and systems-related challenges.

The phased Heathrow Airport reopening will continue over the weekend, with the airport urging passengers to check their flight status before traveling and to arrive early to navigate possible delays.

Woldbye apologized to affected travelers and praised airport staff and emergency responders for their swift handling of a major infrastructure failure. He reaffirmed Heathrow’s commitment to reviewing its power systems and response protocols following this event.

Investigation Into the Heathrow Fire Begins

The exact cause of the fire is still under investigation. The London Fire Brigade has confirmed that the focus will now shift to the electrical distribution systems within the affected substation.

The Metropolitan Police have ruled out any foul play or suspicious activity, indicating that the incident was likely accidental. However, the scale of damage and the vulnerability exposed by the fire have prompted calls for stronger contingency measures at major transport hubs.

Heathrow CEO Woldbye said that a backup transformer failed during the fire, forcing airport systems into a controlled shutdown. This safety measure was necessary to redirect electricity from the remaining substations. However, it slowed the restoration process and highlighted weaknesses in the backup power architecture.

No Injuries, But Concerns Over Infrastructure Resilience

The Heathrow Airport reopening has moved forward without any reports of injury or loss of life. The London Ambulance Service confirmed that no casualties were reported, and emergency services responded swiftly to the blaze.

Despite this, the incident has raised serious concerns about the infrastructure resilience of major airports like Heathrow. Videos shared on social media showed towering flames and thick black smoke rising from the power facility, shocking travelers and locals alike.

Transport Secretary Heidi Alexander stated that the government would be reviewing airport contingency plans, adding that incidents like this show the need for stronger emergency protocols at critical national infrastructure points.

What Passengers Should Expect During Heathrow Airport Reopening

As Heathrow returns to normal operations, passengers should prepare for delays, rebookings, and some congestion throughout the weekend. The airport is working closely with airlines to adjust flight schedules, prioritize stranded travelers, and restore full service.

Travelers are advised to:

• Check with their airline before leaving for the airport
• Arrive at the airport earlier than usual
• Expect limited services in terminals during the recovery period

The Heathrow Airport reopening will continue in phases, with updates expected regularly over the next 24 to 48 hours. While the worst appears to be over, the aftershocks of this large-scale outage may still be felt by travelers and airlines in the days ahead.

Conclusion: Heathrow Airport Reopening Marks Slow but Steady Recovery

The Heathrow Airport reopening is now in progress after one of the most disruptive incidents in recent memory. While Friday saw limited operations resume, full recovery is expected by Saturday. The fire exposed vulnerabilities in power infrastructure and raised critical questions about the airport’s preparedness for such events.

As investigations continue and passengers return to the skies, one thing is clear: resilience and rapid response are just as important as efficiency in managing a global airport like Heathrow.

Passengers are encouraged to remain patient and stay informed as the situation develops. The Heathrow Airport reopening may be a bumpy ride—but it’s already on the runway to recovery.
