Landing fee Filton
What is the current fee, for a Pa28-140.
Living in Bristol many years ago, and based at Lulgsate (Bottom) never needed to go to Filton.
Many times as ground visitor, was there for the Concorde first flight.
Have friends close to Filton, so might go by air from Biggin, rather motor car.
As to route of choice, I would always go cross country, with mil assistance.
