Thick fog is set to cause another day of misery for air travellers, with flights out of London's major airports cancelled or delayed.
Heathrow and Gatwick already have a backlog of passengers. The airports warned this morning that further delays are expected after more cancellations overnight because of air traffic restrictions.
Forecasters had predicted the fog would remain in northern and eastern areas of England and Wales into Tuesday morning but the Met Office has now removed its yellow weather warnings.
Heathrow Airport said on Twitter: "Following yesterday's heavy fog, the Met office has issued another fog warning for this morning. If you are due to fly today, please check your flight status with your airline before travelling to Heathrow."
Gatwick also tweeted: "There may be some disruption to flights due to the fog. Please check directly with your airline."
A Manchester Airport spokesman said: "Like much of the UK, Manchester Airport has been affected by the fog and low visibility over the past couple of days.
"There have been periods where conditions have improved, flights have landed as normal and we have been able to accept diverted flights from other airports experiencing the same issues. However it does look like the foggy conditions could remain throughout the morning, and we would ask customers to check with their airline about the status of their individual flight."
London Fog
It comes after some 129 flights - equivalent to 10 per cent of departures - were cancelled at Heathrow on Monday because of air traffic restrictions caused by low visibility.
London City Airport was closed for flights until around 11am, while Gatwick, Manchester, Liverpool John Lennon, Glasgow, Belfast and Southampton airports were also affected.
