Swiss airports lead in passenger volume as travelers navigate customs

Zurich Airport remains the largest aviation hub in Switzerland, handling 32,593,966 passengers according to 2025 data. It is followed by Geneva Airport with 17,848,370 passengers and the EuroAirport Basel-Mulhouse, which serves the tri-border region with 9,631,209 passengers. Smaller regional hubs include St. Gallen-Altenrhein and Bern Airport, which report significantly lower passenger volumes.

Travelers using Zurich Airport, particularly those from Germany, are advised to remain mindful of customs regulations. While Switzerland is part of the Schengen Area, travelers returning to Germany must navigate different import rules when moving from a non-EU country into the European Union.
