Why spend so much money?
Why not save yourself at least £60 on this flight (and get a decent lunch).
Go to abroad and get the tax back from the fuel, just fill in the form (HO60) with the duty paid fuel chits and the nice man at the C&E will send you a cheque (about £60 for a PA28).
To lazy to fill in the form? fly abroad out of Lydd and you won't be charged duty on the fuel uplifted.
So can you think of any reason why you would want to do this trip inside the UK?
