DUBLIN (Reuters) - Groups representing Europe's largest airlines and airports have warned of chaos and hours-long queues unless countries better coordinate the roll-out of the EU's digital COVID-19 certificate and ensure passengers are processed before arriving at airports.
The European Union's system of digital COVID-19 travel certificates is due to come into force on Thursday, but airports group ACI and airlines representative bodies A4E, IATA and ERA warned in a letter to EU national leaders of a "worrying patchwork of approaches" across the continent.
