Uku Särekanno, a director of the EU border agency Frontex, told an Abta event that some member states were “struggling” to adopt the entry/exit system (EES) and that the situation may not stabilise for one to two years. The EES, which requires non-EU travellers to register biometrics at the border, was first introduced last October and fully rolled out on 10 April, with suspension of checks allowed to prevent queues until September. French police temporarily suspended checks at Dover in May, and Greece will suspend biometric checks for British travellers until September. Abta’s chief executive said problems with the system could hurt demand among British holidaymakers, and On the Beach’s chief executive noted later booking patterns created uncertainty; shares in On the Beach have fallen 30% this year.
