The EU's new Entry-Exit System (EES) — which now obliges over a third of non‑EU nationals entering the Schengen area to submit extra personal and biometric data — has provoked a standoff between airports and Brussels. Airports warn of operational strain, higher costs and longer processing times amid limited staff and technical readiness; EU institutions argue the measure is necessary to improve border security, migration management and traveller rights. The dispute highlights tensions between security aims, data‑protection concerns and practical implementation challenges that could affect expats, short‑term visitors and airlines alike.
