Ryanair has warned that holidaymakers should expect lengthy queues at 15 popular European airports this summer. The airline has blamed the EU’s new entry-exit system (EES) for long passport queues and airport delays, which “continues to create disruption months after its introduction”.EES was rolled out in full in April this year, requiring non-EU nationals to submit biometric data such as facial images and fingerprints when entering the Schengen free movement area.Since the introduction of EES, travel industry heads have criticised the new system for causing hours-long queues at many airports in the bloc.Ryanair said it has identified 15 European airports where passengers are experiencing significant delays due to slow processing times at the border.These include Lisbon, Tenerife South, Madrid, Lanzarote, Alicante, Malaga, Milan Bergamo, Milan Malpensa, Verona, Paris Beauvais, Berlin, Cologne, Frankfurt Hahn, Krakow and Budapest.Ryanair said all these airports are popular destinations for UK families travelling abroad during the peak summer holiday season.Earlier this month, the airline also warned that Palma airport in Mallorca is similarly prone to lengthy queues.Ryanair is advising British passengers to allow extra time for their journey and to be prepared for extended waits at passport control.Currently, border controls have the use of temporary flexibility to suspend the collection of biometric data until the start of September, but Ryanair has joined calls to see this rule extended until early 2027.It says this will give airports and border authorities the time needed to fix faulty kiosks, increase staffing levels and ensure the system can operate efficiently.Ryanair’s Chief Operations Officer, Neal McMahon, said: “Families heading away for a well-earned summer holiday should be thinking about suitcases, suncream and sangria, not standing in passport queues for hours. “The reality is that the EES isn’t working properly and families are paying the price for a system that does not work months after launch. Passengers should not be the testing ground for unfinished border infrastructure.“We support calls from EU Member States to urgently extend the EES flexibilities. This will give airports and border authorities the time to improve the infrastructure, fix the broken devices and hire more staff so that families can travel through Europe without disruption.”Read more: Port of Dover has done ‘absolutely everything’ to avoid summer EU entry-exit chaos
