The new Entry/Exit System (EES) across the EU has caused chaos and lengthy queues as of late - and is set to have a large economic impact, too.

Faulty technology and hold-ups as travellers provide biometric data in the form of fingerprints and facial scans has resulted in long snaking queues at airports.

Europe’s new EES border checks may cause airport queues of up to six hours this summer, IATA warns, urging travellers to arrive much earlier for flights.
