As of 2026, Luxembourg remains the global pioneer, having made all public transport—buses, trains, and trams—entirely free for both residents and tourists since 2020 (excluding first-class train travel). Malta followed suit in 2022, offering free bus travel to all residents with a Tallinja card. In Estonia, the capital city of Tallinn has provided free transit to its residents since 2013, though county-level free bus travel for adults was largely scaled back recently. Many other European nations offer targeted free transport: in the Netherlands, students enjoy free country-wide travel, while Spain has extended its "free commuter train" initiatives for multi-trip ticket holders on Cercanías and Media Distancia routes through much of 2025 and 2026. Additionally, several cities like Montpellier in France and Cascais in Portugal have implemented local free transit schemes for residents. For seniors (usually 65+), countries like Hungary, Romania, and the UK (via the Freedom Pass or similar) provide significant or total fare exemptions, making Europe the leading continent for zero-fare mobility experimentation.
