Raise the landing fees and only charge one rate at the most congested airports. This would encourage bigger planes with less frequency. It would further reduce the economics of RJs.
I think we need to decrease this frequency BS. Too many airplanes that only have 50-70 seats (lots of em empty) clogging up the system. Start imposing min seat rules and slots at peak times at the airports with the worst delays.
