Exactly, the elected positions guide/direct the staff but ONLY when a cross section of members representatives are on the board of directors. An unrepresentative few pushing their own patricular agenda (as a controlling minority) is not healthy at least IMO. Not likely to change in the short term until enough members get upset enough to reflect their "airport opinions" in the voting area.
We have what we voted for and will remain until changed in the short term, for how long is anybody's guess.
Comically enough as predicted before the constitution change vote!
