National Express have now published their Christmas Day Timetables.
As usual they will run half hourly from Victoria to Heathrow from 0345, and a special direct half hourly service to Gatwick airport, every other bus extending to Brighton.
They are also running limited services around the country, including to Glasgow/Edinburgh, South Wales and Cornwall, many via Heathrow.
Premium prices are being charged, as the drivers who wish to work are being paid substantial overtime.
The Oxford Tube will also run their buses from Victoria to Oxford.
