Holidaymakers planning trips to Europe this summer are being urged to check their passports and travel documents well before they travel, as new digital border checks continue to cause delays and confusion at some European airports.

The EU’s Entry/Exit System (EES) is now operating across the Schengen area, replacing passport stamps with a digital record of when non-EU travellers enter and leave participating countries. The system applies also to British passport holders travelling for short stays and records facial images, fingerprints and passport details at the border.
