I have tried to talk to some of the more expensive airfields in the UK about fees but I often find the same attitude, "if you dont like it f... off"
I landed in Lydd a couple of years ago to pick up a mate, I bought 250 Ltrs fuel and still got charged £28 for landing a Mooney. When I complained I was more or less told not to bother comming back. I havent!
I work a lot in France, better welcome, better FBO type facilities & cheaper landings. And they are run by the FRENCH???
