Heathrow Says It’s Fully Operational After Blackout Shutdown

London’s Heathrow airport said it’s open and fully operational following an unprecedented daylong blackout that brought travel to a standstill for hundreds of thousands of passengers at Europe’s busiest airport.

British Airways, the biggest single operator at the airport, said it expects to run about 85% of its schedule on Saturday. Power supplies have been restored to all customers connected to National Grid UK’s North Hyde substation, including Heathrow, allowing operations to resume at the airport, the utility company said in a post on X.
