I am looking for some general advice - this is specific to the UK but may be similar else where.
I know it is possible to hire a private aircraft, I see comments like this on club/rental sites all the time:
Fly ASG members can experience affordable personal air travel for the Channel Islands, France and beyond. Fly ASG offers their services of non chartered aircraft rental to engage customers with a new streamlined approach to business and leisure travel.
Many sites mention the brakes on - brakes off fee per hour, but say you took that trip to the Channel Islands, France, or beyond: how do these companies usually charge for the bit where you will presumably be parked while you work on your sand castles at the beach for the day?
Just to be clear I'm not asking about airport parking etc. but how the owner of the aircraft will charge when it is not flying.
