London’s Heathrow Airport has been forced to shut down entirely after a major fire at a nearby electrical substation caused a widespread power outage.
The closure has disrupted over 1,300 flights, leaving an estimated 145,000 passengers stranded and causing chaos across the global travel network.
Authorities say the fire is now under control, but the disruption is expected to last for several days. The London Fire Brigade has warned that the incident remains “prolonged,” with continued challenges for both travelers and residents. Investigators are still working to determine the exact cause of the fire, but officials say there is no evidence of foul play.
Passengers at Heathrow and other affected airports have expressed frustration over the lack of clear communication from airlines. Many travelers had already arrived at the airport before being informed of the shutdown, while others were stranded midair as their flights were forced to divert.
Several flights bound for Heathrow were rerouted to alternate airports across Europe, including Madrid, Paris, and Shannon in Ireland. Five flights landed at Manchester Airport, but officials there say they are not expecting further diversions. British Airways passengers arriving in Madrid from South America reported standing in long lines with no updates on their baggage or onward travel plans.
In response to the crisis, airlines have rolled out emergency measures. Ryanair launched eight rescue flights between Dublin and London Stansted, while Virgin Atlantic and British Airways have urged passengers to stay home. Some airlines are offering flexible rebooking options, but many travelers say they have received little to no guidance on alternative arrangements.
The shutdown has also led to a sharp drop in airline stocks, with shares of International Airlines Group, which owns British Airways, falling by as much as five percent. Lufthansa and Air France-KLM also reported losses as the financial impact of the disruption continues to grow. Industry experts estimate that the total cost to airlines and Heathrow Airport could reach hundreds of millions of pounds.
Beyond the airport itself, rail services in and around Heathrow have been severely impacted. Heathrow Express, which connects the airport to central London, has suspended all services, while Transport for London has reported severe delays on routes serving the airport. Authorities have advised passengers not to attempt traveling to Heathrow until further notice.
Travelers caught in the disruption have shared their frustration over the uncertainty. Some have resigned themselves to long delays, while others have had to cancel their trips entirely. A passenger heading to New Delhi for a wedding said her trip would be pointless if she didn’t leave within a day, while a man traveling to Pakistan to see his family remained unsure when he would be able to depart.
Many passengers on long-haul flights had little choice but to wait as airlines scrambled to manage diversions. Aviation analysts say rerouting flights midair is a complex challenge, requiring close coordination between pilots, airline operations teams, and air traffic control. The limited availability of alternate landing spots added to the difficulties, especially for flights that had already traveled long distances from Asia, the United States, and South America.
Government officials have pledged a full investigation into the fire and its impact on critical infrastructure. The UK’s energy secretary acknowledged that Heathrow’s backup power system had also been affected, raising concerns about the airport’s ability to handle emergencies. However, authorities maintain that the fire was likely an accident rather than a deliberate act of sabotage.
With no clear timeline for reopening, the shutdown at Heathrow continues to send shockwaves through the travel industry. Passengers, airlines, and businesses reliant on the airport are bracing for further delays, cancellations, and financial losses as efforts to restore power and resume operations remain underway.
