Martin Stew explains all...
63 flights had to be cancelled at Heathrow Airport this morning due to poor visibility. There were also severe disruptions at London City Airport. Both airports have advised passengers to check with their airlines. There was also no service this morning on the Woolwich ferry.
Heathrow Airport has seen queues of passengers waiting to leave as the freezing fog has led to around 60-70 flights being cancelled.
– Heathrow spokeswoman
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!
Passengers in Terminal 5 at Heathrow Airport have bedded down to wait, after many flights were cancelled or delayed due to fog.
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
