For the second time FSR Transport has brought together a round of experts to discuss the topic of Airport Charges Regulation, specifically a possible revision of directive 2009/12/EC. In 2017 Commissioner Bulc and FSR Transport conveyed a high level Executive Symposium on the same topic. This time on a more technical level the seminar tried to find some agreement between airports and airlines and discussed an initial impact assessment. Read the two comments on the discussions by Prof Matthias Finger and Prof Juan Montero.
