No but by a government agency. Presumably the same type you're proposing should operate the whole airport since you're saying the private companies are the issue?

Best example is WTB. Private airport. Built in record time specifically because the government couldn't get their finger out of their backside for years, win win for everyone and a well functioning airport. If we left it up to the government then we'd have another Badgerys Creek on our hands because government means incapable politicians which are no better than the incapable CEOs. If we had a technocratic government my response would be very different.
