Different studies have demonstrated how improving air connectivity increases GDP. In this regard, to promote aviation and ensure its ongoing benefits to society and the market, the EU Commission has published a document, Flightpath2050, that draws aviation's future in Europe. One of the goals set by this document states: "90% of travellers within Europe are able to complete their journey door-to-door within 4 hours.". The first part of this paper analyses 341 airports across the EU and calculates the percentage of the population that can travel door-to-door within four hours, assuming that every possible origin-destination pair is connected with direct flights.
