Free route operations offer significant opportunities to airspace users. Once fully implemented in Europe, it should allow the saving of 500.000 nautical miles, 3000 tonnes of fuel, 10.000 tonnes of CO2 and 3 M€ in fuel cost, every day (source: Eurocontrol).

For air navigation service providers, free route operations improve trajectory predictability, due to a reduction in the divergence between planned and actually flown routes, and reduce the need for coordinations and air-ground communications.
