The old ritual of entering Europe — a passport, a stamp, and you're through — is gone, and its replacement is testing airports at the worst possible time of year.

A stamp replaced by a scan

The European Union's Entry/Exit System, known as EES, began rolling out in October 2025 and was declared fully operational across the Schengen Area by April 2026, Al Jazeera reported. It replaces passport stamps with a digital record: every non-EU national arriving at a Schengen border — by air, rail or sea — now has fingerprints and a facial image captured along with their passport details. The stated aim is tighter security and better tracking of visitors who overstay.

Queues and half-empty planes

The rollout has strained borders. Al Jazeera reported queues of up to five hours at some checkpoints, and cases of flights departing only partly full because passengers could not finish biometric processing in time — a bottleneck the old stamp system never produced.

The disruption prompted three of aviation's biggest bodies — Airports Council International Europe, Airlines for Europe and the International Air Transport Association — to send a joint open letter to the European Commission, warning that the current implementation was causing "severe operational consequences" and putting airports, airlines and border staff under "unsustainable pressure." They asked Brussels for flexibility, including the ability to pause EES processing when passenger volumes overwhelm a facility.

The summer math

The timing is punishing. European airports expect roughly 40 million more passengers in July and August than in the prior two months, according to figures in the industry letter cited by Al Jazeera. The World Travel and Tourism Council estimated that tens of millions of arrivals and billions in visitor spending could be at risk if delays persist. "If lengthy delays become accepted practice, travellers will look elsewhere," the group's chief executive, Gloria Guevara, said. The European Commission did not immediately respond to Al Jazeera's request for comment.

What it means for American travelers

U.S. citizens can still visit the Schengen Area without a visa for up to 90 days in any 180-day period — but that exemption does not spare them from EES. As non-EU visitors, Americans are subject to the same biometric registration, captured at the border booth or at dedicated kiosks on first entry.

The practical takeaway for anyone flying to Frankfurt, Amsterdam, Madrid or another Schengen gateway this summer: build in significantly more time at passport control than in past years, especially when a wide-body jet's worth of arrivals hits the hall at once. Travelers connecting onward within the Schengen zone clear EES at their first point of entry.

Another layer still to come

EES is only part of the EU's new border setup. A separate program, the European Travel Information and Authorisation System, or ETIAS, will eventually require visa-exempt travelers — including Americans — to obtain an online authorization before departure, much like the U.S. ESTA. ETIAS has not launched, however, and its start date has been postponed repeatedly; no confirmed date was available as of publication. For this summer, EES is the system travelers will actually encounter — and, the industry warns, the one that will keep generating long lines unless the EU acts quickly to ease them.
