The new Entry/Exit System (EES) has been wreaking havoc across Europe since its rollout began back in October.Since April, the process has been used across 29 countries and is an automated digital border system for non-EU nationals, including UK citizens, entering the Schengen Area – which includes most of the EU, plus Iceland, Norway, Liechtenstein and Switzerland.Travellers are now required to register biometric details, including fingerprints and photographs. But the new system has caused long queues in airports and in some cases, even led to passengers missing their flights. Budget airline Ryanair even went as far as writing to all of the countries using the EES, urging them to temporarily scrap the system.The impact has been so great that one in 30 UK holidaymakers have changed their destination because of the chaos created by the EES, and one in five say they are likely to, according to research by Holiday Extras.So, where are the worst places for EES delays? Some airports have been struggling with long queues and delays due to the Entry/Exit System (EES) Italy Milan Malpensa Airport, in Italy, has been described as one of the worst hubs for EES delays by travel expert Simon Calder. On the Telegraph’s podcast, The Travel Expert, Calder spoke from personal experience with the busy airport and revealed: ‘I did the fingerprint stuff, it took an hour and I was the first one off the easyJet plane from Gatwick. ‘Then, I went through to the other terminal to check out and it took I think 45 minutes, but they wanted those fingerprints again which is absolutely not in the rules.’Another passenger described similar on social media in April, when the system was first fully rolled out: ‘Two hours after landing and I’m still an hour from clearing passport control. Good job. Good try,’ they fumed. Other airports in Italy have experienced chaos too, including Milan Linate Airport, which saw passengers vomiting and passing out.Around 100 easyJet customers were abandoned at Linate airport while waiting to board a flight to Manchester in April, with three-hour queues plaguing travellers.The airline said the situation was ‘outside of our control’ and issues with the new Entry/Exit System had caused the delays, adding that the hold ups were ‘unacceptable’. The Daily Mail reported at the time that easyJet delayed the Milan flight by 52 minutes to allow customers extra time – but with the crew approaching the end of their safety-regulated working hours, the flight was forced to head off half empty. The saga left customers scrambling for alternative means of getting home, with some only discovering they had missed their flight once it had left without them.

Loads of people missing flights despite arriving hours in advance because of insanely long queues to passport control. No one seems to be in control or to have any idea what to do.’Another traveller said he’d experienced a similar scenario, writing: ‘Having the machines at the start of the queue before going through passport control just caused a massive queue leaving Lisbon.’Meanwhile, one Reddit user said of Lisbon airport: ‘Line was hours long stretching through the whole very long terminal and then outside… Security has stopped using the new system and were stamping passports as fast as they could.’Portugal’s Prime Minister Luis Montenegro has even threatened to suspend the new system – a suggestion which the Mayor of Lisbon, Carlos Moedas called ‘necessary’. There have been several reports of ‘chaos’ at Lisbon airport because of the new system FranceTravel correspondent Calder also flagged Paris-Charles de Gaulle Airport as being bad for EES queues, as well as Frankfurt in Germany. ‘Both of them are huge hubs, of course, and particularly with those you’ve got a lot of people who are flying from various regional airports across the UK into Paris, into Frankfurt to connect,’ Calder added.’And that’s okay if you’re going intercontinental because you don’t need to go through the Schengen Area border – but if you’re trying to connect to somewhere in Europe, it’s going to be awful.’In April, a parent travelling with a child, believed to be at Paris-Charles de Gaulle Airport, wrote on social media: ‘Absolutely ridiculous queue for passport control. EU passport with a child under 12, I’ve been queuing for over two hours and still there’s at least a hundred people ahead of me.’ Paris-Charles de Gaulle, pictured, is another hub thought to be badly impactedCopenhagen Copenhagen is another hub mentioned by Calder, and the airport has even caught the attention of the UK Foreign Office, which has released updated guidance in its travel advice for the destination. It reads: ‘Following the introduction of EES, you may experience delays at passport control when arriving at or departing from Copenhagen Airport on flights to or from non-Schengen countries, including the UK.’You should allow extra time when travelling through the airport.’If you have a short onward connection, you should take this into account when planning your journey.’If you need assistance, for example if you are travelling with young children or have accessibility requirements, speak to airport staff wearing yellow vests who are managing the queues.’ The UK Foreign Office has even issued guidance about Copenhagen airport (pictured in 2022)SpainAlicante Airport is one of Spain’s busiest hubs, and the country’s police union previously reported that the airport is being pushed to ‘breaking point’ over the EES system and lack of staff, according to the Olive Press. Meanwhile, Málaga Airport has also been impacted, and a British holidaymaker was left stranded in the hub with her daughter after missing her flight.Michelle Maguire, 38, and her daughter were due to fly back from Málaga to Liverpool – but did not make it home until 24 hours later after getting held up in travel chaos which eventually cost the family £1,000.Ryanair explained how waiting times are over one to two hours at many Spanish airports, including Málaga, Alicante, Lanzarote, Tenerife South, Gran Canaria, Reus, and Fuerteventura.In a bid to tackle the chaos and make things easier for families and those with disabilities, hubs have brought in some new rules.AENA, the Spanish airport authority, has requested that workers help vulnerable passengers and families with young children avoid the queues. Some Spanish hubs have also battled long queues, pictured is Adolfo Suarez Madrid-Barajas Airport in MadridWhere can I avoid the chaos?Thankfully, there are some popular destinations where the EES doesn’t apply, as they are not in the EU or are outside the Schengen zone. Turkey is one such destination – and as a result, is having a real moment this summer, attracting hordes of tourists. Indeed, exclusive data revealed to the Daily Mail by holiday booking platform On the Beach in April showed demand for trips to the country had jumped by 57 per cent.Cyprus is another sunny spot that holidaymakers can opt for, with beaches, hotels and great weather – but without bothersome EES queues. Over in North Africa, Morocco is also exempt from any EES chaos. For those headed here, Agadir is a coastal gem, and offers an array of resorts and crystal-clear water. It was identified as being the most affordable destination for a summer getaway this year. Visitors can stroll along long stretches of sandy beach, explore vibrant markets and bask in 300 days of sunshine.
