Travelers flying from the UK to Europe are being urged to arrive at airports three hours before their flights due to extensive delays linked to the European Union's new Entry/Exit System (EES). Yvonne Moynihan, CEO of Wizz Air, highlighted that the EES, which requires biometric data collection, has resulted in long queues and missed flights across various European airports. With reports of waiting times reaching up to three-and-a-half hours, especially at popular destinations, travelers are advised to bring water and portable chargers. While the EES was introduced last year, it became fully operational on April 10, causing significant congestion. Some countries, including Greece and Portugal, are temporarily suspending EES requirements to ease the burden on travelers. Despite the European Commission's assertion that the system is largely effective, many airlines, including Ryanair, have criticized the new checks as a source of disruption. Moynihan expressed concerns that the situation may worsen as summer approaches, emphasizing the need for more countries to consider suspending these rules during peak travel periods.
