That is the question? recently completed a landing there in a single (2 POB) and paid the landing fee of £20.40 by debit card only for my flying school to also get a bill for an unpaid landing fee related to my visit. I still had a copy of my receipt and a copy scanned through to the airport. A simple administrative error or pure incompetence? If there was to be a next time, I would take an abacus with me. Perhaps it could help them with their mental arithmetic! beware!
