The warning comes as more Britons than ever prepare to jet off for a summer break. More than half of UK adults are expected to travel abroad in 2026, despite concerns that new travel requirements could lead to disruption at airports across Europe.
Searches for “summer holiday deals” have also surged by 123% in the past three months as families rush to book trips during the peak holiday season.
One of the biggest concerns is the rollout of the European Union’s new Entry/Exit System (EES), which requires British travellers and other non-EU visitors to provide biometric data, including fingerprints and facial scans, when entering the Schengen Area.
Airline industry leaders have warned the new checks could dramatically increase processing times at passport control.
Rafael Schvartzman, vice-president for Europe at Iata, said the system increases passenger processing times from around 20-25 seconds to as much as 90 seconds per traveller, creating a “hard risk” of lengthy queues and missed flights.
Reports have suggested waits could stretch to as much as six hours at some airports and border crossings during the busiest summer travel periods.
As a result, airlines including Wizz Air are advising passengers to arrive at airports at least three hours before departure.
Nicole Kerr, chief executive of transport platform Mozio, said holidaymakers should be prepared for potential disruption.
“UK searches for ‘summer holiday deals’ have increased by 123% in the past three months, as Brits look to secure their travel plans ahead of peak season,” she said.
“While a holiday is meant to be a relaxing and stress-free experience, experts have warned that changes to the travel industry could cause delays and confusion.”
She said the new Entry/Exit System was likely to be one of the biggest challenges facing travellers this summer.
“Passengers travelling to European airports will now have to use the new European Entry/Exit System, which requires biometric data, such as fingerprints and a facial image.
“While the new system is expected to reduce wait times at passport control in the future, Brits have already experienced long delays as the rollout continues.”
Other travel changes Brits need to know about
The EES is not the only change affecting travellers.
Britons have also been warned to prepare for the introduction of the European Travel Information and Authorisation System (ETIAS), expected to launch later in 2026.
Under the scheme, visa-exempt travellers, including UK passport holders, will need permission to enter 30 European countries for short stays.
Applications will cost €20, although under-18s and over-70s will be exempt from the fee.
Meanwhile, travellers heading to the United States are being encouraged to use the Mobile Passport Control app, which allows passengers to complete border information digitally before arriving at passport control.

How families can avoid airport stress this summer
Travel expert Gianni Leone, senior product director at Away Holidays says preparation is key, particularly for families travelling with children.
Parents are advised to:
- Arrive at airports earlier than usual
- Keep passports and travel documents easily accessible
- Pack extra snacks, drinks and activities for children
- Download any required travel apps before departure
- Allow additional time for passport control and security checks
- Pre-book airport transfers where possible
Nicole Kerr warned that delays may not end when passengers leave the terminal.
“Alongside these procedures, travellers will inevitably be met with other challenges which could cause delays, such as airport strikes and long taxi queues when leaving the terminal,” she said.
“In 2025, travellers reported long taxi queues at airports across popular tourist destinations, including the Canary Islands.”
She added: “With experts predicting another busy summer for airports across Europe, long taxi waits could follow similar patterns to last year.”
For travellers looking to avoid further delays after landing, she recommends booking airport transfers in advance. There’s also often an option to use metro and train systems, and even regular buses – but if often needs pre-planning.
