Airport layover document checks: where ETIAS can matter.
A connection can be more than a pause between flights when it changes the route, document check, or border-entry question.
Short answer
Layover relevance depends on the traveller, passport, route, and whether border entry occurs. ETIAS is not live yet, so current preparation should focus on mapping the full itinerary.
- List every airport and country in the route.
- Check whether baggage collection or airport change requires entry.
- Separate airside transit from entering a country.
