European skies and airports risk saturation. Already some 800 million passengers pass through Europe's more than 440 airports every year. Each day there are around 27,000 controlled flights – that means 9 million cross Europe's skies each year. 80% of these flights are operated within the EU.
The European Commission envisages the following solutions: creating the Single European Sky by removing national boundaries in the air, to create a single airspace: improving safety tenfold, tripling airspace capacity, reducing air traffic management costs by 50% and reducing the environmental impact by 10%.
