European airports are seeing long delays for non-EU travelers after the EU’s Entry/Exit System (EES) was fully implemented in April. Officials and travel reporting attribute the congestion to new biometric passport checks—requiring face and fingerprint scanning—along with system unreliability and slower processing at border control. The delays are affecting multiple destinations, with travelers reporting several-hour waits at airports including Lisbon, Amsterdam, Copenhagen, and Milan. UK passengers are among those told to arrive early, with some warnings that they may face queues lasting up to six hours. The International Air Transport Association has previously warned the system could cause “severe disruptions” during peak season, and additional reporting suggests some member states are still struggling to fully adopt the process.

EES is designed to create a digital record valid for three years, so travelers who have already enrolled should be processed more efficiently on later trips. The European Commission also promotes a preregistration option via an official “Travel to Europe” app to complete parts of the entry requirements before reaching the border. Coverage also notes that not all countries and travelers are subject to EES in the same way, with exemptions for EU, EEA and Swiss citizens and specific country arrangements varying on the ground.
