No, excise taxes are not needed. Simply stop subsidizing the airlines. Make them pay for their security, pay for the ATC’s and pay for the air rights like the RR’s have to for track right of way. Why not make them pay for the terminals and move general aviation to smaller airports near convenient railroad stations for the trip to the city.
I suppose you have not heard of the Airport and Airway Trust Fund. There are a host of taxes on air travel including per seat, per segment, and per gallon of fuel taxes. Many if not most commercial airports also charge landing fees and other charges. General aviation aircraft less than business jets (and even most of them) avoid those airports for that reason.
