Brexit has been a nightmare for dual-citizens like me - and it's about to get worse

Brexit has been a nightmare for dual-citizens like me, and the article says it is about to get worse as Europe adds more layers of travel authorization and border checks. The account describes a problem in Hong Kong when the writer, travelling on an Italian passport because their British passport had expired, was blocked by an automated system. As of February, UK entry requires an ETA (or a UKVI process), and the application asks for an address; the writer’s “usual address” is the UK, which the system flagged as not permissible for their situation. After intervention by a British Airways supervisor and UK border authorities, an exemption was discussed. The article links this to a broader summer disruption: the EU’s Entry/Exit System (EES) became fully operational in April, while Ryanair warned of hours-long delays at Spanish airports. Greece, later followed by Portugal and Italy, suspended biometric checks for British travellers, and ETIAS is scheduled to arrive later this year at €20, matching the UK ETA fee of £20 every two years.
