• Figures are only available for EU countries, Switzerland, Iceland and Norway.

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 was in 2019 Heathrow – Edinburgh with 1,196,921.

Among other European (non-EU, not Switzerland, Iceland and Norway) countries, based on airport statistics, no other country than Russia, Ukraine and Turkey has domestic routes with more than 1 million passengers.

The St. Petersburg Pulkovo Airport – Moscow (three airports) route was used by 2,965,331 passengers in 2013.^[17]

• • Madrid – Barcelona had 4,627,000 passengers in 2007, meaning a reduction by 34% in 2010, partly because of a new high-speed railway. The decline has continued from 560 weekly flights in 2010 to 380 in 2012.^[18]
