Heathrow Airport has seen queues of passengers waiting to leave as the freezing fog has led to around 60-70 flights being cancelled.
While many flights out of London airports have been delayed or cancelled the cold weather has also caused travel disruption on the roads and railways:
- There was congestion on a number of major road routes, while a section of the A1(M) between junctions 39 and 40 in Yorkshire was closed.
- On the railways, overhead wire problems caused 50-minute delays in the rush-hour between Bedford and Luton, while a broken-down train at Watford Junction in Hertfordshire also caused hold-ups.
- An electrical supply problem led to delays to train services between Seaford and Lewes in East Sussex and a signalling problem caused hold-ups to services in and out of Brighton.
- In Scotland, a broken-down train at Bathgate caused to delays between Edinburgh and Airdrie.
We expect the fog to lift between 9am and 10am. Visibility is already improving.
There have been some delays as well as cancellations. There is bound to be a bit of a knock-on effect during the day. Also, some European airports are also affected by the cold weather
Gatwick Airport has said that there is no disruption to flights due to the fog, despite notices on its website saying many flights had departed later than scheduled:
There is no disruption at Gatwick this morning due to the fog. We hope you have a great journey with us!

London City Airport have tweeted help from different airlines for passengers who may have had their flights cancelled, after at least twenty departures were cancelled and many more were 'indefinitely delayed,' you can check flight details for both departures and arrivals here.
Heathrow Airport has explained why fog causes such huge delays at airports;
When there is reduced visibility, drivers have to leave more space between them and the car in front. The situation is no different with aircraft. And if there is more space between planes, not as many planes can land or take-off each hour – which can mean delays and cancellations.
The airport added that cancelling flights in advance introduces space into the schedule and aims to reduce disruption for passengers by:
- Allowing airlines to rebook passengers onto un-allocated seats on other flights, significantly reducing the number of passengers that cannot travel that day
- Giving passengers clear information about the status of their flight so they can rebook from home or their hotel
- Helping to avoid flights being cancelled at short notice, significantly reducing the chances of people staying at terminals overnight
