Heathrow and gatwick have flights taking off and landing every 90 or so seconds.
They cancel some flights so they have a chance to grit the runways every hour or so.

It's perfectly believable.

If it's like that, then yes
But that's not what you see on the news. However, I'd understand better if they delayed the flights so they can grit the runways, rather than cancelling them.

Then everyone would be delayed.
I figure it's better for them to cancel some and then the other planes take off on time.

But that's unfair
to the people who has them cancelled.

Then everything would just get progressively later until the system falls apart
They start off cancelling UK internal flights because people can use trains instead. Then northern europe, and so on. It does make sense.

Then why has London City shut?

Because it's shit.

because it has a very short runway and no margin for error, what with it being in the river.
So if it gets slippy they don't risk it.

Plus I imagine there is a visibility issue.

Mind you, Embra airport was shut all yesterday and that has quite a lot of snow facilities.
