Regional statistics

Europe

Busiest flight routes inside the EU, UK, Switzerland, Iceland and Norway. Figures are only available for EU countries, Switzerland, Iceland and Norway. Passengers of domestic routes in countries is fewer than 1 million, except for Russia, Ukraine, and Turkey, based on airport statistics among other European countries (excluding EU members, Switzerland, Iceland, and Norway). The St. Petersburg Pulkovo Airport – Moscow (three airports) route was used by 2,965,331 passengers in 2013.^[8]

The UK has not reported for 2021 and parts of 2020, due to Brexit, but data is available from EU/Eurostat countries for flights to/from the UK, but not for UK domestic or UK intercontinental flights. The multiple airports of London lower the airport-to-airport figures; the busiest UK domestic route in 2019 was Heathrow – Edinburgh with 1,196,921.
