Almost all transatlantic flights from the UK to New York, Boston and Philadelphia have been cancelled today because of Winter Storm Stella, the severe snowstorm predicted in the north-east US.
British Airways has cancelled all its flights to the two main New York airports, JFK and Newark, as well as Boston and Philadelphia.
BA hopes an early-morning Boston-Heathrow flight will operate, but all other eastbound services have been grounded.
"We are sorry for the disruption to your travel plans and are doing all we can to minimize the effect the weather forecast will have on our US operations," the airlines said.
