[SINGAPORE] At least 11 flights between Singapore and London have been cancelled or diverted after Britain’s Heathrow Airport said on Friday (Mar 21) that it will be closed until midnight (8am on Mar 22, Singapore time).

Six of the 11 flights were cancelled, leaving thousands of passengers’ plans in disarray.

In response to The Straits Times’ queries, Singapore Airlines (SIA) said flights SQ305, SQ317, SQ319 and SQ321 which were scheduled for departure from London on Mar 21 have been cancelled.

Flight SQ318, which was supposed to depart Singapore at 12.45pm on Mar 21, was also cancelled.

Flight SQ308, which departed Singapore on Mar 21, will return to Singapore and is expected to land at 4.30pm. The flight will subsequently be cancelled.

SIA said it will provide assistance to the affected passengers, including hotel accommodation and arranging alternative flights or land transport.

SQ322, which departed Singapore on March 20, was diverted to Germany’s Frankfurt Airport. SQ306, which departed Singapore on Mar 21, will be diverted to Paris’ Charles de Gaulle Airport in France.

Qantas told ST that flight QF1 is on its way to London and has been diverted to Paris. The airline has arranged buses to take customers for an estimated nine-hour-long ride to London.
