European airlines have warned the European Commission that new border control rules were causing chaos and would likely worsen during the upcoming summer holidays.The new entry-and-exit (EES) rules were introduced in April as a tech-friendly innovation to avoid stamping passports of non-EU citizens when they entered the Schengen area, which comprises 29 states.One of its aims is to prevent irregular migration by deploying automated systems that register the person's name, travel document data, biometric data, fingerprints and facial images. The date and place of entry and exit as well as entry refusals are registered.But the new system has instead caused chaos, with reports emerging of British tourists complaining they had missed their flights because of long queues despite arriving more than three hours in advance at the airport.Ryanair says passengers are used as guinea pigs for a half-baked new system. REUTERSInfo"Passengers have already been forced to queue for extended periods outside terminal buildings and on exposed aprons because border control facilities cannot process arrivals quickly enough," airline and airport lobbies the Airports Council International, A4E, and the International Air Transport Association, said in a letter to the EU Commission.Half-empty planes"Airlines face half-empty planes at gate closing time, while passengers are stuck in border control queues," it said.Speaking to the BBC, British tourist Anne Robinson from Dunbarton complained she had missed her flight home in Rome because of a 90 minute queue and that a large number of EES machines appeared not to work.A European Commission spokesperson said earlier this week that a meeting would be organised with representatives of the industry in the next days. "The entry exit system was launched progressively in October last year after all member states had given their declaration of readiness to do so," spokesperson Markus Lammert said. "All efforts are being made to limit the impact on travellers from outside the EU."Mr Lammert said that the impact was "limited" in most EU airports but acknowledged that some states may have had difficulty deploying enough borders guards, appropriate infrastructure, and automated control solutions.In a separate letter, Ryanair joined aviation associations in asking EU states to suspend the roll-out of the EES measures this summer. Airports such as Tenerife South, Palma, Alicante, Malaga, Milan Bergamo, Krakow and Paris Beauvais are experiencing major disruptions, with further congestion expected as we enter the busiest weeks of summer, Ryanair said.The European Commission says it will meet airline industry representatives soon to discuss EES issues. REUTERSInfo“As schools break up and Europe enters the busiest travel period of the year, it is clear that EES is still not ready for peak summer volumes. Passengers and families should not be used as guinea pigs for a half-baked passport control system that risks creating long queues, missed flights and unnecessary stress at airports this summer," Ryanair’s Chief Operations Officer, Neal McMahon said."It is as simple as postponing EES until September, as other EU countries like Greece have already done. Ryanair calls on European governments once again to delay the implementation to protect passengers, families and airport operations during the school holiday rush, instead of forcing holidaymakers to endure needless passport control chaos.”
