Gatwick Airport reports no trains to the airport at present:
As a result, several lines of route are suffering from a combination of flooding, blockages from fallen trees, power supply failure or potential landslips. We will not be able to gauge the full extent of this damage or the prospect for operating services safely until daylight. Currently we are working closely with our colleagues in Network Rail to prioritise the clearing and proving of routes to be safe before trains can operate. This means that train services are SUSPENDED until this work is complete and we do not expect this to happen until much later this morning.
We will update this site with our progress as we work to restore services and passengers wishing to travel today are asked to check before they set out for the station to ensure that services are running.
Passengers are advised to check the latest travel situation before starting their journeys via southernrailway.com, nationalrail.co.uk or on Twitter @SouthernRailUK Ticket flexibility has been increased to allow passengers to change their time of travel if necessary.

Heathrow delays are better than yesterday with a small number of delays and cancellations. LHR live flight information here.

Luton has some delays – details here.

Well worth checking before you leave for the airport through.
