Heathrow Airport has been shut all day today after a devastating electrical fire – causing chaos for the around 220,000 who were due to travel through the UK’s busiest airport today.
It was forced to completely close after its main electrical substation exploded and set alight less than two miles away in the west London suburb of Hayes.
At least 1,357 flights have been cancelled, diverted or delayed and people are being advised not to make journeys to the airport as it remains closed until 11.59pm today.
A spokesperson for Gatwick Airport, the closest London airport to Heathrow, told MailOnline: ‘We are aware of the situation at Heathrow Airport today and we are supporting by accepting diverted flights as required.
‘Flights are operating from London Gatwick as normal today.’
Online flight tracking service FlightRadar24 said the closure would affect all of the scheduled 679 arrivals at and the 678 planned departures from Heathrow today.
Some planes already on their way to London managed to land at other UK airports.
British Airways, American Airlines, Virgin Atlantic, United Airlines, Air Canada and Delta have suffered the largest number of cancellations and diversions.

Dozens of flights have been diverted to Amsterdam, Frankfurt, Lyon and other European cities, stranding tens of thousands of people abroad. Some planes were even forced to turn back and set down in New York, Los Angeles, Mumbai and Delhi, where Air India has now cancelled all its flights to London.
A Heathrow Airport spokesperson said: ‘Due to a fire at an electrical substation supplying the airport, Heathrow is experiencing a significant power outage.
‘To maintain the safety of our passengers and colleagues, Heathrow will be closed until 23h59 on 21 March. Passengers are advised not to travel to the airport.’
The airport, which sees a plane land or take off every 45 seconds, announced its closure at 2am today and ordered passengers not to come to its terminals.
The fire broke out at around 11.30pm on Thursday and around 70 firefighters worked throughout the night to bring it under control. Police have launched a major incident as investigators look into the cause of the fire.
Ryanair has launched eight rescue flights for passengers affected by the airport closure, running two from Dublin to Stansted and two more from Stansted to Dublin today – with the same four extra flights also added for tomorrow.

British Airways said: ‘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.’

A spokesperson for nearby London Stansted Airport said: ‘London Stansted is currently operating as normal, we have capacity for a small number of diverts but as yet we haven’t received any requests.’
Birmingham Airport is also assisted with taking flights diverted from the closed Heathrow Airport.
A spokesperson told MailOnline: ‘There will be no delays to Birmingham Airport’s own customers, due to any diverted Heathrow aircraft into BHX.
‘Airports regularly take diverts as part of normal operations, and flights inbound to London Heathrow will use multiple airports around the UK, and Ireland, or alternatively may return to their departure airport.
‘We will assist with landing any diverted aircraft during the Heathrow closure today and work with those LHR airlines to repatriate their customers upon arrival into Birmingham.’
MailOnline understands Manchester Airport accepted five diverted flights this morning but that the airport is not expecting to take many more diversions today.
