At least 120 flights diverted
It’s going to be a chaotic day for some travellers with flight tracking website Flightradar24 saying that at least 120 flights in the air bound for Heathrow will have to divert due to the airport closure.
Scores of flights are already being diverted to other airports, with Qantas Airways sending its flight from Perth to Paris and a United Airlines New York flight heading to Shannon, Ireland. Some flights from the US were turning around mid-air and returning to their point of departure.
A United Airlines flight from San Francisco was due to land in Washington, D.C. rather than London. British Airways and Virgin Atlantic diverted flights to nearby Gatwick.
Heathrow is one of the busiest two-runway airports in the world with about 1,300 combined take-offs and landings a day, according to its website.
“Heathrow is one of the major hubs of the world,” said Ian Petchenik, spokesman for FlightRadar24. “This is going to disrupt airlines’ operations around the world.”

Commenting on the blaze, a spokesperson for Heathrow airport said to expect significant disruption over the coming days.
“Heathrow is experiencing a significant power outage across the airport due to a large fire at a nearby electrical substation. Whilst fire crews are responding to the incident, we do not have clarity on when power may be reliably restored.
“We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens.
“We will provide an update when more information on the resumption of operations is available. We know this will be disappointing for passengers and we want to reassure that we are working as hard as possible to resolve the situation.”
The London Fire Brigade has said that its crews remain at the scene of the fire in Hayes.
“Please continue to keep windows & doors closed due to smoke & avoid the area. This will be a prolonged incident, with crews remaining on scene throughout the night,” it said in a post on social media.
