(UK, EU AIRPORTS) – British travellers are being told to allow much more time at EU airports because the Entry/Exit System, or EES, has lengthened passport control checks and raised warnings of queues of up to six hours in some locations.

UK government guidance says EES started on 12 October 2025 and applies to UK nationals travelling short-stay to the Schengen area. The guidance says each passenger can take extra time to process, and travellers should expect to wait longer than usual at the border.

The sharpest warning came from the airline industry. IATA said routine passport checks that previously took around 20 to 25 seconds can take about 90 seconds under EES.

Its director general warned that queues of “three, four, five, six hours” were possible if staffing and technical problems were not fixed before the peak summer period. That warning has turned EES into a practical concern for holidaymakers, airlines and airport operators as summer traffic builds.

EES replaces manual passport stamping with biometric registration and electronic entry and exit records. It applies to most British passport holders travelling to the Schengen area for short stays.

That means the system does not cover every trip from Britain into Europe. Ireland and Cyprus are not part of Schengen, so EES does not apply when travelling to those countries.

British travellers do not need to register in advance, and there is no fee for EES registration. The process happens at the border on arrival.

The first crossing is usually the slowest. Passengers may need to provide fingerprints and a facial image at a kiosk or booth before they can complete border checks.

That first encounter with the system sits at the center of current delay warnings. A process that once relied on a quick passport stamp now includes biometric collection and the creation of an electronic travel record.

The timing matters most at busy airports handling large numbers of non-Schengen passengers in tight departure and arrival waves. Even a small increase in processing time can build into long lines when many flights land close together.

IATA put numbers on that pressure. If a routine check rises from 20 to 25 seconds to about 90 seconds, the effect is not marginal at a crowded border hall.

Airline and airport operations depend on steady passenger flow through security, border control and boarding gates. Slower passport processing can spill backward into terminals, especially where staffing is thin or equipment runs into problems.

That is why warnings about six-hour airport queues have drawn attention well beyond border agencies. Airlines face delayed boarding, airports face crowding, and travellers face longer waits at the point where journeys begin or end.

Spanish airport guidance already reflects that strain. Guidance from the Spanish airport operator uses a 3-hour arrival rule for many non-Schengen departures, aligning with the more cautious advice now being given to British holidaymakers flying home from busy EU destinations.

The adjustment is simple but not minor. Passengers who once arrived with a modest buffer before departure now face pressure to build in far more time, especially on routes where non-Schengen traffic is heavy.

The effect will not be uniform across Europe. Border halls differ in layout, staffing and passenger volumes, and the warning from IATA tied the worst delays to unresolved staffing and technical issues.

That leaves airports with little margin during peak periods. A system designed to modernize border records can still create bottlenecks if kiosks, booths and officers cannot process passengers at the rate demand requires.

British travellers heading to Schengen destinations for short stays are the main group affected by these changes. The same is not true for trips to Ireland or Cyprus, where EES does not apply because those countries are outside Schengen.

The distinction matters for families piecing together multi-stop holidays and for passengers using connecting routes. A journey to Spain, France or Italy can involve the new checks, while a trip to Dublin or Cyprus does not trigger the same process.

No payment is attached to registration, and no pre-trip application is required under the guidance cited for EES. That removes one source of administrative burden, but it does not remove the time pressure at the airport itself.

Travellers still face the practical reality of longer border processing on arrival at the external Schengen frontier. Once fingerprints and a facial image are taken and the record is created, later crossings may move more quickly, but the first one is expected to take longer.

That first-contact slowdown is central to the present concern around airport queues. Summer travel peaks concentrate demand into morning and late-afternoon banks, when several flights can feed the same passport control area within minutes.

Airports and airlines have little room to absorb sudden spikes if each passenger takes about 90 seconds instead of 20 to 25 seconds. The math changes fast in crowded terminals.

The warning also reaches the return leg of a holiday, not only the outbound journey from the UK. British passengers flying home from busy EU airports can hit the same border-control friction on the Schengen side before departure.

That helps explain why Spanish airport guidance now favors a 3-hour arrival rule for many non-Schengen departures. Longer waits at passport control can erase the time passengers once counted on for bag drop, security and the walk to the gate.

EES has often been described in technical terms, but its immediate effect is physical and visible: longer lines, slower-moving booths and tighter timing for passengers. The system replaces stamping with biometric and electronic records, yet the transition has shifted attention to queue management.

Industry concern has focused on what happens if peak summer traffic arrives before staffing and technical problems are fixed. In that setting, the warning of “three, four, five, six hours” becomes less a headline than an operational risk.

British travellers now face a more demanding border routine at many Schengen entry points. The process is free and requires no advance action, but the cost is measured in time, especially on the first crossing under EES.

With EES now in force since 12 October 2025, the practical message from governments and the airline industry has converged: arrive earlier, expect waits to run longer than before, and do not assume a quick passport check at a busy EU airport.
