How much?
 

A colleague and I took his twin to a 24 hr regional airport a few months ago. I booked in with the handling Agent.
"That'll be £30 for the landing, £80 for overnight parking, do you need fuel (yes please) and what time are you leaving in the morning (it was early) Oh, then we will have to make a surcharge - of £432 to open the door and let you airside!"
Ouch!
