An estimated 1,351 flights, including those operated by Air India, were cancelled or diverted Friday after London’s Heathrow airport shut down for the day. This was after a fire at an electrical substation in the western part of the city triggered a widespread power outage.
There is no word yet on when power will be restored to the airport, authorities told the BBC.
Apart from chaos at Heathrow – one of the busiest airports in the world and largest of five serving London and nearby areas – more than 16,000 homes in the UK capital lost power.
As many as 120 flights were in the air over Heathrow, either having just taken off or about to land.
Among those due were the AI129 service from Mumbai and the AI161 from Delhi. The former will return and the latter has been diverted to Frankfurt in Germany, the Indian carrier said in a statement.
“All our remaining flights to and from London Heathrow, including AI111 (another Delhi-London service) have been cancelled for 21 March. We will update about resumption as soon as we have information.”
