Heathrow says it is expecting a full day of “100% operation” after the airport was shut over a loss of power – but passengers have been warned of further disruption.
A limited number of flights resumed overnight following an almost day-long closure after a fire at a nearby electrical substation triggered a “significant power outage” on Friday.

The closure of Europe’s busiest airport led to more than 1,000 flights being cancelled and disrupted the travel plans of as many as 290,000 passengers.
On Saturday morning, a Heathrow spokesperson said it was now “open and fully operational” but that passengers should still check with their airline.
The airport said hundreds of extra staff were in terminals and more flights had been added “to facilitate an extra 10,000 passengers”.
Police have said the cause of the fire is believed to be non-suspicious, while London Fire Brigade (LFB) said its investigation would focus on electrical distribution equipment.
Heathrow boss Thomas Woldbye said the flights that took off on Friday night would help make sure the airport had “operations in place” for Saturday morning.
Several airlines, including British Airways (BA), Air Canada and United Airlines, said late on Friday that they would restart scheduled flights both to and from Heathrow.
