How can you make money out of an airfield without charging people to use it? That includes the people renting land/buildings for business on the airfield as much as the pilots landing there and the owners keeping their aircraft there.
If a company has just purchased an airfield, I would assume they have looked at the books. If the previous owners could not make a profit from charging users, then I assume the new owners have already identified where prices have to go up. I guess Wigglyamp has a lease with a rent fixed for a period so probably not much chance of increasing that charge during the period. Ah, but landing fees can be put up at any time, at the drop of a hat, as can parking fees....
The guys who bought the airfield want to make a profit. They won't make money out of increasing landing fees.
And we will loose another airfield to a housing estate.
