The point I am making is that £25 is not a huge amount of money in aviation or event terms.
A couple of weeks ago I paid £29.50 for a ticket to see Paul Weller in concert.
A month ago I took the kids and the good lady to the Zoo and it cost me £35.
My point is that all things are relative (especially in Norfolk!!) and if you don't think it's good value it's not good value. I believe that with a good offer to join the PFA with the £25 ticket, memberships would go up significantly and revenues year on year would grow.
