(EUROPE) — European airlines and airports are asking Brussels to pause the EU Entry/Exit System during the busiest summer weeks, warning that some border checkpoints are already slowing travelers by hours. If you are flying into the Schengen area this month, expect longer queues until member states get more flexibility or the rollout is eased.

The call comes from ACI EUROPE, Airlines for Europe (A4E), and the International Air Transport Association (IATA) in an open letter to Commission President Ursula von der Leyen. The groups say the system has reached a “critical point” and is creating “severe operational consequences” at some airports.

Their complaint is not about the idea of digital borders itself. It is about timing and capacity. The groups say waits at some airports have reached five hours during peak periods, a level that strains border police, airport operations, and flight schedules at the same time.

They want two things. First, member states should be allowed to completely suspend EES immediately whenever passenger demand exceeds local capacity, at least through July and August. Second, Brussels should create a permanent flexibility mechanism by September for exceptional situations.

The pressure is rising because EES only became operational in April 2026. The system replaces passport stamps for most non-EU travelers with digital registration, including biometric data such as fingerprints and facial images. That adds more steps at the border, and those steps take time when queues are already long.

The timing is brutal for airport operators. The letter says EU airports are expected to handle 40 million more passengers in July and August than in the previous two months. That surge lands just as many travelers are encountering the new process for the first time.

Some airports are coping better than others. The Commission says efforts are underway to limit the impact on travelers, and it says the effect has been limited at most airports. But some member states are still struggling with staffing, infrastructure, and automated equipment.

That split is familiar across Europe’s border network. Big hubs with more gates, more staff, and better automation can absorb delays more easily. Smaller or under-resourced airports feel the strain first, and inbound banks of flights turn those delays into missed connections, missed hotel transfers, and longer immigration halls.

Airlines are also looking at the operational cost. A five-hour queue does not just frustrate passengers. It pushes aircraft turnaround planning, crew duty times, and connection banks closer to the edge. When one border desk slows down, the ripple can hit the rest of the arrival schedule.

The dispute also lands in a busy summer for European travel more broadly. Passengers have already faced tighter border checks, stronger documentation rules, and more pressure on airport staffing than in past seasons. EES adds another layer, and the industry wants a pressure valve before peak traffic peaks harder.

The comparison with normal passport stamping is simple. Stamps were messy, but they were fast. EES is cleaner on paper, but only if border systems keep pace. When they do not, the line moves at the speed of the slowest scanner.

Travelers with tight connections should plan accordingly. Build extra time into itineraries that involve first entry into the Schengen zone, especially at airports already reporting heavy summer arrivals. A missed connection caused by border delays is easier to avoid on the booking side than to fix at the airport.

Carriers and airport groups want the Commission to act before the heaviest traffic hits. The industry’s next deadline is September, when it wants a permanent emergency mechanism on the books. Until then, summer arrivals into Europe may continue to feel the full weight of a system still settling in.
