• •Intra-EU international travel represented another 36.4% of the overarching European aviation passenger framework in 2024.

Who operates in the industry and how is it structured?

The European domestic aviation market operates under a liberalized single aviation market framework, allowing any EU-registered airline to operate domestic routes (cabotage) within any member state.
