What is your share of services? What do you feel is the marginal cost
of
providing services to you?

Why is the marginal cost what's relevant (rather than a pro rata share
of
the total cost)?

Because the services are in place due to airlines, and you have no choice
about using them. If there were not GA, the cost would be virtually
unchanged.

And if my immediate relatives and I didn't ride the subway, the subway
system would still be in place and the cost would be virtually unchanged. So
why should my relatives and I be required to pay a fare to ride the subway?

For just about any transportation service with a large clientele, you can
say of any single client--or any tiny subset of clients--that their marginal
cost is much less than their pro rata share. If marginal cost is your basis
for saying what everyone's fair share is, then it turns out that everyone's
fair share is near zero.
