Fog hit flights today, with dozens of services having to be cancelled.
Heathrow had to axe more than 80 flights and there was also disruption to services at London City Airport.
The poor visibility led to the Woolwich Ferry service in London being suspended.
It was the second day running of flight disruptions, following delays and cancellations yesterday due to anti-austerity strikes across Europe.
