Currently the BAA web site says
Tuesday 21 December - updated at 12:30
Heathrow is operating around one third of a normal flight schedule until 06:00 on Thursday 23 December. Please check the live flight information board below which shows the current status of each flight. If the flight status shows ‘contact airline’, your flight will not be operating today.
But according to the BBC
Prime Minister David Cameron says he is "frustrated" over the lengthy delays to air travel caused by snow at Heathrow Airport during the weekend. He said cabinet had discussed the widespread travel chaos "extensively" on Tuesday, as thousands of passengers remain stranded across the UK.
He said the second runway at Heathrow would be open within hours.
I wonder if the BAA has been told that the second runway will be open shortly?
Edit: it is also reported that BAA has refused the help of the army to clear the snow
