How Airlines Were Preparing for EES and ETIAS in Early 2024

The readiness question behind the rollout

IATA's February 2024 analysis treated EES and ETIAS as a major airline-operations issue. At that stage, the article described the then-expected rollout timeline and argued that carriers needed to prepare for new document checks, new interfaces and a more complex pre-departure decision process.

Why EES looked operationally difficult

The article warned that EES would not cover every traveller group at once and that many cases would still require manual verification. It also noted that system responses such as OK, NA and NOK EES were not yet detailed enough for frontline agents to rely on without extra checks, which could increase workload and check-in congestion.

ETIAS transition periods were part of the problem too

IATA also highlighted the planned ETIAS transition and grace periods, during which carriers would still need to rely on existing document checks for many passengers. The broader message was that digital authorisation systems might eventually streamline compliance, but the early phases could be messy unless airlines received clearer tools, better data and realistic implementation support.
