The Safety Valve Holding Europe’s Borders Together Just Closed

The safety valve that has kept European border queues moving all summer is about to be shut off. When the Entry/Exit System reached full operation across the Schengen external frontier on 10 April, member states were handed the right to partially suspend biometric registration for up to 90 days, with a possible 60-day extension on top. Portugal leaned on that allowance hardest, scaling EES back at Lisbon, Porto and Faro to survive peak season. Most of those windows expire in early September, and the European Commission has signalled it does not intend to grant further relief.

EES replaces passport stamping for non-EU visitors with a biometric file: fingerprints, a facial image and a running tally of days spent inside the 29-country Schengen area. The first registration is the slow one, because it has to be built from scratch at the booth. Airports running the system at full tilt have reported border processing times stretching by as much as 70 percent, and peak-hour waits of up to three hours. Lisbon abandoned an early test outright after queues reached seven hours and staff reverted to manual checks.

The phased approach was designed precisely to avoid that outcome. Rollout began on 12 October 2025 with a trickle of travellers, and by February the Commission reported that most member states had pushed past the halfway mark on registrations. The theory is that the pain is front-loaded: once a large share of frequent visitors already exist in the database, subsequent crossings verify in seconds rather than minutes. Whether that crossover point has actually arrived at the busiest airports is the question September will answer.

For travellers, the practical advice is unglamorous but useful. Arrive earlier than you would have last autumn for any first crossing into Schengen, particularly at Iberian and Mediterranean gateways that have been operating with reduced enrolment. Carry a physical passport even where kiosks are available, since fallback to manual processing remains common. And expect the shoulder season to be the real stress test: September traffic is heavy, the grace periods are gone, and ETIAS, the separate travel authorisation scheme, is still queued up behind all of this.
