Notes

1. 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.
2. 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.
3. The St. Petersburg Pulkovo Airport – Moscow (three airports) route was used by 2,965,331 passengers in 2013. ^[20]
4. 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. ^[21]
5. Includes very detailed statistics regarding busiest passenger flight routes to or from and within this region
