Hundreds of aircraft that served at London airports were suspended or deferred in thick mist.
By daytime some of the 62 flights to or from London Heathrow were erased and a further 380 was delayed for more than 15 minutes.
That means that more than one of three airs were broken.
British Airways only showed 45 options and delays at 237 in the mid west of London, it is the most expensive airport in the UK.
The London City 62 saw their release and 46 seconds, although Gatwick was not able to get it. cut off 173 occasions. The figures were published by FlightStats flight data company.
Smoke reduces publicity for pilots and air traffic controllers, and means that the safe distance between planes has increased. This will eliminate the normal pattern of movements and land.
The contracts also delayed the trains that attended Gatwick. A National Rail Queries website statement reads:
The nice and Thameslink received a number of reports from drivers that caused heavy smoke to run at a reduced pace due to visibility reduction.
When thick smoke is present, drivers can not see signs from their normal astounds and continue to work safely, they must drive less speed so that they can see signs.
