Apologies if someone else has already posted this:

Do the fees paid by the commercial airlines completely cover the
costs of building and operating airports and the air traffic control
system?

If not, then passengers are also subsidizing commercial aviation.

The only fees that commercial airlines pay a

1. Landing fees (merged into ticket costs).

2. Gate rentals (again merged into ticket costs).

3. Fuel taxes only on non-revenue flights (ferrying, repositioning,
training)

They pay no fees for use of the ATC system (It comes from direct ticket
taxes)

The bottom line: Airlines are really non-players in the debate and are
pimping user fees as a means of inhibiting competition from high-end GA.
