BA warns of 'knock-on disruption' due to snow

British Airways has said it is doing everything it can to help passengers whose flights have been disrupted by bad weather at Heathrow. A spokesman said:

We are also offering customers who no longer wish to travel today and tomorrow the option to rebook their flight to a later date.

Due to the severe weather yesterday, there will be knock-on disruption to flights today and we would strongly advise customers to check the very latest status of their flight via before coming to the airport.

Only customers with a confirmed booking on a flight which is operating should come to the airport.

More than 400 flights were cancelled at Heathrow yesterday, and hundreds of people spent the night on the floor as they waited for flights to be rescheduled.
