British air passengers returning home are being advised to arrive at European airports about three hours before their flights, due to delays linked to the EU Entry/Exit System (EES). Multiple outlets report that the EES replaces traditional passport stamps with a digital record and involves biometric checks for non-EU travellers, including biometric verification at border control. The system has been rolled out gradually across Europe since October 2025 and has been fully operational from last month, according to reporting. Airports have said some travellers have encountered long queues and significant waiting times at border checks since the change. Against this backdrop, an airline executive is reported to have urged passengers to build in extra time before departure, with specific guidance of arriving three hours early when travelling via EU airports. The reports focus on operational impacts at border control rather than changes to the underlying requirement for travel documents. Overall, the guidance is presented as a practical response to congestion at airports while the EES processes are implemented and adjusted.
