As European airports prepare for increased passenger volumes this summer, Wizz Air's UK boss Yvonne Moynihan has issued a warning to travelers to expect long queues due to new biometric checks under the Entry Exit System (EES). Passengers are advised to arrive three hours before their flights to avoid missing connections, as delays have already caused some to miss return flights. The EES, which requires biometric registration, has recorded nearly 80 million entries, with 35,000 refusals of entry since its implementation. While some airports report seamless travel, hotspots like Spain and Portugal are experiencing significant delays, with queues extending up to three and a half hours. Moynihan remains optimistic, encouraging travelers to continue booking holidays, citing no anticipated flight cancellations. However, she noted that if oil prices remain high, fares could increase in the future. The European Commission has allowed temporary suspensions of biometric checks to alleviate long waiting times, especially as the summer peak approaches.
