The EU's new digital border system, EES, has caused delays and long queues at European airports during the summer, prompting warnings for travelers to arrive early and prepare for extended wait times.

• The EU's new Entry/Exit System (EES) requires non-EU travelers to provide biometric data at border controls, causing delays at some European airports during summer peak travel.
• Queues of several hours have been reported at certain airports, with some passengers missing flights due to long waits at EES checkpoints.
• The EES system is being tested this summer, with some airports experiencing issues with technology and staffing, while others have seen smoother operations.
