BA advised that only customers with confirmed flights come to the airport, saying people should check with their airport.

British student Ophelia Conheady - who is stranded in New York - has told Daybreak that the lights going out in Manhattan was a "terrifying experience."
Danny Lopez, British Consul-General in New York has told Daybreak that the Consul has no idea how many Brits are stranded in the States.
Mr Lopez said: "We don't have any numbers or figures right now. Over the past 48 hours we've only had 14 calls from Brits wanting more information."
After more than 80 pupils from local schools on trips to New York are reported to be safe.
Cecilia Motley, Shropshire Council cabinet member for education and skills, said:
The safety and well-being of our pupils is everyone's number one concern, and I know it's been a worrying time for parents who are seeing the images of destruction on the television news.
We are told from the group leaders in New York that the worst of the storm has passed, and apart from some high winds the weather is not actually too bad.
All the pupils are in good spirits and are being well looked after, and parents are being kept up-to-date by the schools regarding when their children will be flying home.
Parties of children from three Shropshire schools on trips to New York are reported to be safe, well and in good spirits.
More than 80 pupils from Idsall School in Shifnal, Shrewsbury's Priory School, and Lakelands School in Ellesmere, now face a wait to learn when they can return to the UK.
Idsall School's chair of governors, Mark Blackstock, said:
Pupils have been encouraged to text message their parents to let them know that they are OK and we are speaking with the staff in New York to get as much information for parents as we can.
We appreciate parents may be worried, but we can assure them that the pupils are safe and in good spirits, with teachers following the appropriate advice from the New York authorities.
We will keep parents informed of any developments regarding flights back as there will inevitably be some disruption from so many cancellations taking place.
As both a fellow New Yorker and a proud Londoner I am deeply saddened to see your great city under such pressure from Hurricane Sandy. I am hugely encouraged by your response, that of public employees of NYC and indeed the response of emergency services and the American people up and down the east coast.
Rest assured the people of London stand shoulder to shoulder with the people of New York at what is clearly an immensely difficult and challenging time.
As ever, with all best wishes
