just a small clarification
Eurocontrol does not charge you for flying (a popular misconception). The route charges part of Eurocontrol is a centralised debt collector for all Member States. Each Member State sets its rules, amounts and conditions - Eurocontrol merely applies them according to an agreed formula, based on weight, and distance flown, countries crossed etc.
The money collected by Eurocontrol is retured to the Member States, less a trivial charge for the cost of running the service.
