Snow has hit airports around the country as London hubs brace for disruption.
More than 150 flights have been cancelled at Heathrow this morning, while Cardiff, Bristol, Southampton and Bournemouth airports were closed.
Heathrow is still operating normally, however snow is falling in the London area and there may well be more cancellations as the day progresses.
Operations at Gatwick are running normally at this stage, but officials at both airports are asking passengers to allow extra time for their journeys and to check the status of their flights before travelling to airports.
Train services are likely to be subject to delays or reduce service schedules.
Stansted remains open and operating normally, although snow is expected in the area this afternoon. There are no reports of snow at Manchester airport and it is operating normally.
Bristol and Cardiff airports have since reopened, but flights are subject to delays and cancellation at short notice.
A statement from Cardiff Airport said: "The runway has reopened at 10:30 and the airport is now able to accept flights.
"Please be aware that flights can continue to be cancelled by airlines and customers should continue to check the latest information on the airport and their airline's website.
"If you are journeying to the airport please be aware of difficult driving conditions and disruption to public transport.
"Please check travel information websites and allow extra time for the journey to the airport."
British Airways said, "Significant snowfall expected across the UK today (Friday) and over the weekend, [is] affecting aircraft flow rates and [causing] a high demand for de-icing.
"Further cancellations for later today are now being actioned with customers notified by text if their mobile number is present in the PNR."
So far the airline has cancelled 67 shorthaul roundtrips and four longhaul roundtrips today.
