Heathrow Airport was forced to cancel more than 80 flights after thick fog hit the south of England yesterday.
There was also disruption to the schedule at London City Airport, while the Woolwich Ferry service in London was halted by poor visibility.
Norwich Airport had to divert some flights to other airports and Southampton Airport reported delays to flights from the Channel Islands.
The fog came at a bad time for UK airports, with many enduring a second day of flight disruptions. Travellers up and down the country suffered on Wednesday as services were cancelled and delayed because of strikes against rising unemployment and austerity measures throughout Europe.
British Airways, one of the airlines affected by the poor visibility, assured customers on flights disrupted by the foggy conditions that it was doing everything it could to help.
"We have been contacting customers on affected flights, who have the choice of rebooking or claiming a refund, and are advising customers to check ba.com for the latest flight information," BA said.
"We apologise to customers for the inconvenience and thank them for their understanding."
