European Commission (EC) rules on airport charges have been applied unevenly across Member States according to a new report. Airport charges account for 10 per cent of airline operating costs, and are reflected in ticket prices. The EC’s directive on charges aimed to increase competition in the Europe’s airport market, and applies to 75 airports in the European Economic Area. The EC’s latest report shows that since the directive was introduced in 2011 larger airports have opened up the decision making process around charges. Some airports remain less clear on the charge process. The EC’s response to the problem is to encourage more cooperation between airports and the Thessaloniki Forum of Airport Charges Regulators, a new independent supervisory authority.
