This is both on the airlines and the FAA. Airlines are for-profit businesses, as they conveniently forget when they’re trying to pretend that they’re public transportation to get government subsidies. They use taxpayer funded infrastructure and services to make money. They should accept reasonable regulation to allow fair and even usage of said items. It’s pretty well known how many planes an hour can use a piece of pavement and yet the airlines cram more than that in because it makes more money to use 3 subcontracted RJs instead of one of their planes and run a schedule that melts down whenever there’s weather (because it’s still more profitable even with meltdowns). The FAA’s the only government regulator that has in their mission promoting the same thing they’re regulating. They need to just regulate and do a better job of it. Maybe in a few years they will, but even if voters do better I doubt there’ll be major change in the direction of the FAA.
