The Daily Mail reports that passengers have also been taking to Twitter to bemoan the situation. One wrote: "Great, so much for my flight from London City Airport this morning."
The cancellations come after the Met Office issued a warning for fog in the south east on Monday night.
The Met Office forecast for London suggests that fog will persist throughout the day but that it should lift into Wednesday.
"On Tuesday night, mist and fog should reform widely to give another murky night, although it will be much milder than of late, with temperatures reaching double figures in places.
"On Wednesday, it will be mild but grey, however the developing breeze should progressively lift mist and fog, eventually developing some breaks to perhaps give some late bright or sunny intervals, mainly in the south. Temperatures could reach 12 °C."
