• •Indirect digital distribution is managed by large multinational travel platforms and European-centric niche aggregators.
• •According to Eurostat, international extra-EU transport dominated traffic flows, accounting for 50.1% of all passengers carried at the EU level in the first nine months of 2025.

What drives demand in the industry?

Demand within the online air booking sector is closely linked to macro-economic indicators, regional demographic mobility, and the continuous evolution of digital commerce interfaces. The widespread deployment of mobile payment systems and high-speed broadband infrastructure across EU member states has made online channels the default mechanism for itinerary planning.
