It's somewhat ironic that the legacy airlines fought tooth and nail to prevent the airports from being given this responsibility. But the EU regulators (mostly the EP) insisted fearing if they didn't everyone would get the Cryanair (lack) of service. And now? Everyone gets the Cryanair level of service.
The regulation, and National law, provides for effective, proportionate, and dissuasive penalties. It's about time that these penalties are applied.
Also, give the responsibility back to the airlines. The EU/National regulators have no problem getting them to apply the regulations, including Cryanair type airlines.
