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.
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:
Passengers in Terminal 5 at Heathrow Airport have bedded down to wait, after many flights were cancelled or delayed due to fog.
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;
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
London City Airport has urged passengers to check with their airlines after severe weather overnight:
