Europe’s summer travel season is being overshadowed by a blunt and unusually urgent warning from one of the continent’s top aviation figures.
Just as millions of tourists prepare to fly into Europe, airport leaders are raising an alarm that the new Entry/Exit System is struggling under pressure, creating uncertainty about whether airports can handle the peak travel surge.
Stefan Schulte, head of ACI Europe, the region’s airport industry association, has publicly warned that the system is not functioning as smoothly as expected.
His comments reflect growing concern inside the aviation sector, where executives say they are facing “sleepless nights” over how border processing will cope with the summer rush of international arrivals.
The warning has turned what was already a controversial border upgrade into a full-scale operational concern for airports, airlines, and travelers.
What the airport industry is warning about
The European Union’s Entry/Exit System was designed to modernize border control by replacing traditional passport stamping with biometric registration.
Travelers entering the Schengen Area now undergo facial scanning and fingerprint verification, creating a digital record of movement across European borders.
But according to airport industry leaders, the rollout is proving far more complex than anticipated.
Schulte’s warning highlights a growing gap between policy expectations and operational reality. Airports are reporting significant slowdowns in passenger flow at border checkpoints, particularly during peak arrival windows when multiple international flights land within minutes of each other.
The issue is not just technical. It is logistical. Airports must now process large volumes of travelers through systems that require additional steps per passenger, increasing the time needed for each border interaction.
Why “sleepless nights” matter for airports
When aviation executives describe “sleepless nights,” it reflects more than frustration. It signals operational risk.
Airports operate on tightly timed systems where delays at one checkpoint can cascade across the entire travel network.
If passengers spend longer at border control, baggage claim congestion increases, flight connections become tighter, and airlines are forced to adjust schedules or absorb delays.
For summer 2026, this pressure is amplified by record-high travel demand across Europe. Major hubs such as Paris, Amsterdam, Frankfurt, Madrid, and London are already preparing for peak passenger volumes, and even small inefficiencies can create large-scale disruptions.
The concern is that the Entry/Exit System, instead of streamlining travel, may temporarily slow it down during its most sensitive rollout phase.
What is happening at Europe’s borders
The Entry/Exit System (EES) applies to non-EU travelers entering the Schengen Area for short stays. Instead of passport stamps, border officers now collect digital entry and exit data, along with biometric information such as fingerprints and facial images.
The system covers 29 European countries and is intended to strengthen border security, reduce overstays, and modernize immigration tracking.
However, the transition period is where the strain is being felt. First-time users of the system require full biometric registration, which takes longer than a standard passport scan. Even repeat travelers must still pass through updated digital checkpoints that are not yet uniform across all airports.
This inconsistency is contributing to delays, confusion, and uneven processing times across different countries and terminals.
Why tourists are experiencing delays
For travelers, the impact is immediate and practical.
Airport queues at passport control are taking longer, particularly during peak arrival hours. Families, tour groups, and long-haul passengers are the most affected because they tend to arrive in large batches.
The biggest issue is timing. A system designed to improve long-term efficiency is currently slowing down the short-term flow of passengers. Even small delays per traveler can add up to multi-hour wait times when thousands of passengers are processed through a single window.
Airports are also dealing with a learning curve. Staff are adapting to new procedures, passengers are unfamiliar with biometric steps, and infrastructure such as kiosks and scanning stations is still being optimized.
The summer travel pressure point
Summer is the most demanding season for European airports. Passenger traffic spikes due to tourism, school holidays, and international events. This year, the Entry/Exit System is being tested at exactly the moment when airports are least able to absorb disruption.
The aviation industry’s concern is that any inefficiency will be magnified under peak conditions. A 30-second delay per passenger can quickly scale into long queues when multiplied across wide-body aircraft arrivals.
In practical terms, this could mean longer waits at major tourist destinations, increased stress on connecting flights, and potential bottlenecks at key hubs that serve both European and long-haul international routes.
Why this is also a political issue
The warning from ACI Europe is not only operational but also political. By publicly urging officials to “stop pretending” the system is working smoothly, airport leadership is signaling frustration with the pace of rollout and communication between regulators and operators.
Large infrastructure changes, such as EES, require coordination among governments, airlines, airport authorities, and border agencies. When one part of that system is not fully aligned, pressure builds quickly on the front line where passengers experience delays directly.
This has raised questions about whether the system was fully stress-tested under real summer travel conditions before being deployed at scale.
What travelers should expect next
In the short term, airports are expected to continue adjusting staffing levels, expanding biometric kiosks, and refining passenger flow systems to reduce congestion.
Travelers are being advised by industry groups to allow significantly more time at airports, especially when entering or leaving the Schengen Area. Airlines are also reviewing boarding procedures and connection buffers to reduce the risk of missed flights.
As the system stabilizes, processing times are expected to improve. However, aviation leaders warn that this summer may be the most difficult transition phase before efficiency gains are realized.
Why it matters
Europe’s Entry/Exit System is designed as a long-term modernization step, but its rollout highlights the real-world tension between digital transformation and travel infrastructure capacity.
For travelers, the immediate effect is simple: longer waits and less predictable airport experiences. For airports, it is a stress test of whether Europe’s border systems can handle modern travel demand without slowing down mobility.
And for policymakers, the warning from airport leaders is clear. A system designed to improve control and efficiency must also work in practice, especially during peak travel season, when millions of passengers depend on it to function smoothly.
As summer demand intensifies, Europe’s airports are not just managing passengers. They are managing the transition to a new era at the border under pressure.
