UK airlines are hoping to resume flights to and from storm-lashed New York.
British Airways had to axe most of its services to New York and neighbouring Newark, but hopes to get flights away to both cities later on Wednesday.
It will be the first time since Sunday afternoon that BA has been able to operate to New York and Newark due to superstorm Sandy.
Virgin Atlantic, whose services have also been disrupted, confirmed it would resume services to the two cities with the first flight due to leave Heathrow for New York this afternoon.
Virgin is also putting on an extra flight which will leave Heathrow for New York at around 1.50pm and fly back from the hurricane-hit city later.
The airline said it was able to operate normal services to and from Boston and Washington DC.
A Virgin spokeswoman said: "We continue to thank our passengers for their patience and apologise for the inconvenience caused to their journey. We advise all passengers to check our website www.virginatlantic.com for the latest updates and advice on rebooking their flights."
BA is currently able to operate normal services to four other US east coast cities - Boston, Baltimore, Washington DC and Philadelphia.
BA said: "Customer safety with regards to Hurricane Sandy remains our highest priority and following advice from the US authorities we are cancelling the majority of flights to and from New York and Newark on Wednesday.
"Customers with confirmed flights only should come to the airport. We are doing all we can to help customers whose flights have been cancelled and will look to use larger aircraft on some routes when the full flying schedule resumes to help get customers to their correct destination as quickly as we can. Customers should continue to check ba.com for the very latest information."
