The airports which serve London are all continuing to operate despite the snow.
Heathrow said conditions were fine and it was not expecting any problems.
Gatwick said it was operating as normal but passengers should allow plenty of time for their journey to the airport.
There have been minor delays at Stansted and de-icing trucks had to be used. Luton also said they have had some delays to flights. Both airports advise passengers to allow extra time for their journey and to check the status of their flight with the airline before travelling to the airport.
