With Heathrow Airport shut on Friday, the impact of disruptions is expected to extend well beyond Britain’s largest travel hub, potentially costing the airline industry hundreds of millions of pounds.
The chaos in global air travel caused by a fire at an electrical substation supplying the airport could last days, if not weeks, according to an aviation expert. As of early Friday, hundreds of flights to and from Heathrow have been canceled or diverted. Airline analytics firm Cirium estimated that “upwards of 145,000” passengers could be affected.
Shukor Yusof, the founder of Singapore-based Endau Analytics, an advisory firm that focuses on the aviation industry, told the financial losses from the shutdown could be in the “hundreds of millions of pounds.”
The fallout “will cause chaos, undoubtedly, for the weekend and into next week because they have to resolve all those flights that couldn’t come in, all those problems that have piled up because of this shutdown,” he said.
Heathrow was the world’s fourth-busiest airport in 2023, according to the most recent data, with a record-breaking 83.9 million passengers passing through last year.
Yusof said a closure like this could affect entities beyond airlines and travelers. It’s a “whole network of people involved” in running the operations of an airport and adjacent areas, ranging from retailers, cargo firms, jet fuel suppliers and surrounding communities that depend on the airport for their livelihood, he added.
Airlines rely on precisely coordinated networks to ensure planes and crews are in the right place at the right time. Now, dozens of carriers must rapidly restructure their operations to reposition aircraft and staff.
“At the moment, I think that the real focus is how to mitigate the impact of the airport closure on airlines and also on the people who work there,” Yusof explained, as it could take days, or even weeks, for airlines to clear the backlog of passengers.
British Airways said it is redirecting inbound flights already on their way to Heathrow to other UK airports, and it advised passengers on flights originally scheduled for Friday from Heathrow not to travel to the airport until further notice.
“This will clearly have a significant impact on our operation and our customers and we’re working as quickly as possible to update them on their travel options for the next 24 hours and beyond,” the airline said in a statement sent to .
