It depends on a number of things...
Firstly, the instrumentation in place in both airports. If the departure airport is a regional airport with basic (or no) ILS in place, then fog may ground aircraft. A major airport will let you land in pretty much any fog conditions.
Secondly, the aircraft type. Modern jets (like A320s) have no problems with fog; it gets more difficult with old props (like F50s).
Thirdly, and this is often forgotten, the rating of the crew. Crew have to be rated for flight in particular conditions. While major airlines will usually have crew rated for all conditions, smaller or cheaper operations (including the likes of Ryanair) often have crew that are not cleared to operate in severe weather, and will therefore have a flight grounded where another crew would not.
Finally, it is often more about logistics than the actual take-off and landing. Fog forces increased separation between arriving and departing aircraft. For an airport at capacity (such as Heathrow), this means that you simply cannot allow every scheduled flight to take off. In that case, priority is generally given to larger aircraft on long-haul routes. At present, BA at Heathrow have made the decision to cancel all domestic flights, as there is still the option to travel overland for such journeys (not so great for connecting passengers, mind).
(Personally, I would have taken a couple of 747s or similar from oversubscribed schedules such as LHR-JFK and run a 'round-robin' route to the major domestic airports to collect connecting passengers, but then I don't run an airline...) |

It depends on how foggy but if hte weather is bad at the airport to take off from then yes it's cancelled or delayed until it clears up. |

I belive Heathrow has ILS CAT 3...which is a system on the runway that allows the planes to land with 0 visibility, all by autopilot and stuff like that...
So....Its alright..
take a look....

Could be because most planes come from somewhere else to drop people off before they pick you up and that's where the fog problem comes in. Also, many planes may be stuck at the gate because where they're going is also fogged in. |

They advise you to ring your airline before you leave home. The fog is set to last the weather on tv said for at least another 48hrs. |

No, planes can take off fine in fog its just that planes dont like landing in fog, but because planes cant land it means that they cant fill up with people and depart. Today all internal flights were cancelled in the UK from Heathrow because its foggy all over. |

Either or both |
