The system, which requires non-Schengen Area travellers to supply biometric data at borders in 29 European countries,has caused widespread queues since it became fully operational in April. The Liberal Democrat MP stressed: "Passengers travelling to Europe shouldn't be punished by a broken, malfunctioning border system that is entirely out of their hands."

She added: "I have twice asked the government to explain how they are improving the situation, and both times I have been told only that they are working to 'encourage' the European Commission and member states to minimise delays.

"The government needs to take a far firmer stance with European counterparts, and press them, collectively, to suspend EES until at least September."

Destinations such as Greece suspended the checks altogether in bid to lure back British travellers, and several airlines have asked passengers to arrive three hours before their flights to allow for extra processing time at the airport. Some travellers have ended up missing their flights due to the queues.

ACI Europe director general Olivier Jankovec said: "Looking ahead, fixing the Schengen Entry-Exit System must be Europe’s immediate priority.

"Long, unpredictable and unacceptable waiting times at border control have started acting as a deterrent to travel – and undermine the standing and reputation of Europe as an efficient and welcoming destination," reports Travel Weekly.

While ACI Europe figures showed a growth in passenger numbers of 4.3% in the first three months of 2026, it was followed by just 1.3% in the second.

The Entry/Exit System (EES) replaced manual passport stamps with an automated digital system. It records biometric data like fingerprints and facial images, making it easier to spot any overstayers in the Schengen Area, which is capped at 90 days within an 180-day period for people without a visa.
