SINGAPORE – Passengers travelling from Singapore and London’s Heathrow Airport are advised to check with their airline on their flight’s status after Britain’s Heathrow Airport said on March 21 it will [be closed until midnight](https://www.straitstimes.com/world/europe/uks-heathrow-airport-closes-for-day-after-fire-at-nearby-substation) (8am on March 22 Singapore time).
In response to The Straits Times’ queries, Changi Airport Group (CAG) said six flights are scheduled to depart from Changi for Heathrow Airport between 12pm on March 21 and 1.30am on March 22.
The affected flights included SQ318, BA16, QF1, BA12, SQ322 and SQ306.
“The respective airlines will decide on whether their flights will operate as scheduled. We advise passengers to check with their airline on their flight’s status,” said a CAG spokesman.
Passengers can check on the status of flights departing from and arriving at Changi on CAG’s website.
ST has contacted Singapore Airlines on how the closure of Heathrow Airport will affect passengers flying out from Singapore to London.
Heathrow Airport experienced a significant power outage due to a fire at a nearby electrical substation supplying the airport.
Fire crews are responding to the accident but there is no clarity on when power may be reliably restored, a Heathrow spokesperson told Reuters in an e-mail, and added that they expect significant disruption over the coming days.
According to flight tracking website FlightRadar24, at least 120 flights will have to divert due to the airport closure.
Dozens of diversions to other airports were already occurring, with Qantas Airways sending its flight from Perth to Paris and a United Airlines New York flight heading to Shannon, Ireland.
A United Airlines flight from San Francisco was due to land in Washington rather than London.
Heathrow was the world’s second-busiest international airport in 2024 behind Dubai, according to travel data firm OAG.
