So it seems like one possible upgrade is simply to a club with "more
availability". And that caused me to wonder about instead having a club

"More availability" for you means "less availability" for the other
members, unless the club is going to be adding airplanes as part of this
hypothetical initiative you are proposing. If 1/3 of the members bought
this "premium" membership that, say, doubles their scheduling rights,
the other 2/3 would be seriously impacted and basically see the value of
their shares decreased.

How about this: set up a system where members can buy and sell "points"
to/from each other. That way at least the people whose availability is
being decreased by your extra points can be compensated. Of course that
may not work because the club's fleet policy may be counting on not
everyone using all their points.
