Snerk. No one has ever won over landing and airport charges or en route charges. The industry is too fragmented to stand collectively or to even have a cogherant collective body to speak on it's behalf.
And if you do stand out from the crowd in arguements with airport authorities, ASA or CASA, your own industry "colleagues" who stand to gain from your efforts, are the first to try to pull you down. Tall poppy syndrome!
Two choices: buy a bottle of Vaseline or move to another airport.
P.S. Good luck anyhow. I hope you do get some satisfaction!
