EUROCONTROL Data Snapshot #37 on aviation connectivity across Europe

Our data

Our 37th EUROCONTROL Data Snapshot takes a look at three European capitals to analyse how aviation connectivity varies across the continent.

Based on door-to-door journey time, EUROCONTROL offers indicators providing a deeper understanding of the level of connectivity at major European cities. The flight choice indicator provides an understanding of the various booking options from a certain origin. To measure the connectivity between a specific city and the other European countries all departure airports within 90 minutes’ drive from the city are considered in the analysis. For instance, for Brussels the calculation considers departures from 28 airports, including Charleroi and Liège but also airports in neighboring countries like Lille or Eindhoven.

The map shows the aviation connectivity for Brussels (left), London (center) and Sofia (right) for direct flights to EU States and the UK in a typical week in September 2022 (04-10 Sep.) compared to the European average.

Brussels shows above average connections to typical holiday destinations such as Portugal, Spain and Italy but also good links to Scandinavia and Eastern European States. It shows below average connectivity to the Netherlands and Germany which is partly due to the good road and rail accessibility to major cities. London shows better than average connections to almost all European States which is partly owed to its geographical island location. A particularly high connectivity from London is visible to Ireland and the Netherlands, followed by Portugal, Spain, Italy, Belgium and Germany. In contrast, Sofia shows average or below average direct flight connections to all European States with a particularly low frequency to the Netherlands, Ireland and Portugal.

Considering the large number of European Institutions in Brussels, it is not surprising that Brussels is among the best-connected cities in Europe. However, other capitals such as London not only offer a good daily connectivity but also a notably higher frequency of flights than European average.

Technical Bits: Destination that can be reached within 2 hours drive are not taken into account for flight connections. More information on the EUROCONTROL aviation connectivity indicators can be found on the European Connectivity app at
