From a commercial perspective airports charges are excessive with some airports collecting direct pax charges in excess of €30, yet you still have to pay to use the runway, and then more charges to handle the aircraft. The airport experience can cost €50 before you leave the gate.
The most prominent person sharing this opinion is Michael O'Leary and he's damn right in this regard. Unfortunately his airline forcing the airports to be more efficient (it's OK!) at the same time gives them too little means to be profitable
