Letting european airlines pay for "domestic" intra-european flights where all other airlines flying into the EU do not have to pay is a direct threat to all european based airlines that do compete on an international level. But it is right in line with the current political direction in many european countries where it is absolutely normal that politicians do their best to get rid of the european based airline business. Of course the politicians do not care when they can fly whenever they want with their military VIP transports (in my country a fleet of several A340s, A319ACJ and quite a few global express). Simply put: more taxes from european based airlines while non-EU airlines get directly financial help if they buy airbus aircraft.
