Some years ago, two of my former colleagues were diverted into Biggin Hill on a scheduled flight when most of the other London airports were closed by fog. The flight was from Eindhoven to one of the London airports - not sure which but not Gatwick. Since they lived in Redhill, they managed to avoid the bus arranged for the passengers and just got a taxi home.
They were pleased to a) get home earlier than they would have and b) get to use an unusual airport (for a business traveller).
